The Latest Tool to my collection.

I have had this for some time but it only had a 5.3 meter extenction ladder on it,  

for some job;s it was not long enough.

I picked up a ladder that is 6.1 meter closed and will extend to 11 meters.

I was LOOKING at it and thought it would make a great antenna, I was thinking about shunt feeding it and also Top loading it.

Has anyone any Ideas, thay might have   Email vk3xq@yahoo.com.au

 

This is how I get to tune and work on my antenna's in the air.

 I also use it to get into the tree's to cut them back I ware a safety harnes

I have been looking for this photo for many year's my wife put it in a safe place.

I took up Triathlon at the age of 45 years, I was 15stone/96kgs quit unfit smoker & heavy drinker, I did not even own a pair of runners, the only thing in my faver was I raced bike's from the age of 14 year's of age.

It took me 3 years to get into shape, my main interest was the Olympic distance event 1.5km swim/40km bike/10km run I finished 2nd in my age group for the series over the year.  

 

Rob's Hydroponics I have turned to growing our Vegetables with Hydroponics as the Birds can't get at them, the system, I use is the Dutch bucket system if want to know anything about it.  Youtube it.  

 

Below The Boom for my 40 meter 3element mono band yagi 15.680 meters long 60mm dia 5mm wall thick.

 

 

Well I have made it to 71 years of age, I only have another 29 years to go for 100! 

Then I will get a Telegram from the KING Haaa

A Photo of Crazy Rob on his Birthday gift, A Scott Spark 750 Mountaion Bike with all the latest bits, Dual suspension, Hydraulic disk brakes and many other bits, worth $3000.

​I have been building a mountain bike Track for some time on the 50 acars of land as it's ideal with many large hills nothing is safe from my plans, I even use the steps at the back of the house and  the Kangaroo tracks in the bush, many log jumps and some very steep down hill runs.

 

 

Crazy Rob What Next!

 

I have been told not to eat the mic before, But never to eat my radio!

Thanks to my (DLR) Komal for the hard work making the Radio cake, She had never seen a Ham radio before, So made it from a photo on the internet and I can even eat the buttons

I have just installed another tower. To install 3x6el yagis for 6 meter band EME with vertical polarization & elavation, BUT I HAVE NOW BUILT 3X7EL YAGIS INSTEAD, 

You will see in the photo above a pipe sitcking out the side of the tower and a heavy steel cable that goes to just above were the coils of coax is and the other end goes to the tower it is a gin pole system there is so much weight that the masting would bend and brake, I used this system to lift my 160 mts top loaded vertical 26 mts high.

 

This is the latest antenna project 3 x 7 element 50 mhz yagis vertical polarized with elevation  spacing 5/8 wave 12ft apart for EME and DXing.

H/B 3 way power divider 25mm square x 3mm, square inside dia  19mm with 12.7mm round center tube length 1.483mm.I was going to use 10mm copper tube for the centre section but it did not give me the right impedence, I was looking on one of the websits and seen they were using alum but they were using solder tabs screwed to the alum, there was not enough space for the screws inside mine, so I cut 70mm of copper tube and inserted 60mm into the 12.7mm x 1.42mm alum and screwed 3 stainless steel through the alum and copper tube on both ends I grinded both ends of the screws flush,  it works fantasic match swr is 1.1 from the tx to antenns. 

The elevation setup is a Kenpro KR500 elevator mounted below the cross boom connected with 3mm stainless steel wire around the cross boom and  attached to elevator tube , the crossboom is mounted to a boom to mast bracket C channel 100x50mm,  there is sleved through a length of 50mm x1.6mm alum tube with 2 length of 50 mm PVC tube split and forced inside, and the 40mm x3mm cross boom fits inside so it can twist This is all my desingn  

(Design DL6WU) Boom length 7.233mm. Boom 32mm square elements 10mm dia.

It has taken me 12 weeks to build the base for the tower and complete the whole job.

Antenna Info BOOM 7.233mm long, Gain 9.8dBd 11.9dBi, multplyed bye the stacking gain. 3db beamwidth 52 deg, Freq 50.150 Mhz

I used VK5DJ's Calculator to build the antenna's 

Tower 4 section 2 meter each  8 mts total  hight with a thrust bearing mount on top of  tower and 5 mts of 48.44mm x 4.47 mm wall of scaffold tube out the top. Mounted through the thrust bearing on the top of the tower. I have used 1.6 meters of 60mm x 5mm wall alum and I have sleved it with 50mm PVC split and ramed inside and it slides over the 48.44mm masting so when I mount the 30 meters 3 element mono band yagi, I can rotate them independently I use a rope connect to the rear of the lower antenna and the rotator turns the the main masting to the 6 meters array I use this system on some of my other tower. the Rotator I used is an Emotator 1102MXX, The only thing I missed out on doing is inserting another piece of alum inside the 48.44mm to stop it flexing so much. When I tilt the system over to change a few things I will add them then 38.3mm x 3mm will fit inside but I will also try add another piece inside the 38.3mm I think that 32mm will go inside it gives me 0.3mm it will be close  

Feed with  LDF450 Coax approx 40 mts long to the power divider and 3 lengths RG214 coax about 9 meters long to each  antenna.

 

Later on I hope to move my 30 meter 3 element mono band yagi and mount it below the 6 mts array, So I can complete my 3 element 40 meter full size yagi on the other tower as it is a lot higher

I have add a photo of the elevation system

Above a photo of the elevation system you can see the inner boom 40mm x 3mm and the outer tube 50mm x 1.6mm wall with PVC sleve inside not seen, attached to boom to mast mount with 4 exharst U bolts 52mm dia, on the mast pipe I have used 8 exhaust U bolts.You can see the stainless steel cable 3mm one pair  to lift the other to make sure it dose not go to far, and also give it a start to drop as it only relies on the front weight to drop down I have not quite got the balance wright you can see the yellow rope I have added 600 grams to make it drop, The elevater is a Kenpro KR500 it was never built to do what I am doing with it Hi.

You will note the outrigger's I use the same system with PVC sleve on either side the right hand side is out 400mm more than the other side so I have put a steel pipe sleve inside the boom and loaded it with lead to balance the system.

Also note the antenna to boom bracket's with 2 exhaust U bolt's so there is no way the antenns will slip   

 

How I calculate the angle of  my antenna's & elevator controler.

I had this Digital Angle sprit level laying around and was not sure what I could do with it, I tryed climing onto the roof and lineing the antennas up with the MOON at differant angles it worked ok but I was never quite sure if thay were right.

I drilled a hole in the bottom and taped it to 1/4 x 20 w/worth, It works great I just get the bubble center and adjust elevation to 10 deg segments and mark dial as you can see 40 deg simple.

 

The Result's of all the hard work setting up the EME syestem

Decodeing Bert S57RR calling Tom DF6HT I was decodeing Bert for about 30 min

 

Decodeing Parker W5ADD calling me for quit some time but because of Parker's noise we did not make a 2 way QSO

I am so happy about the resualt's I have had so far, I never expeded to see such a result, I have been LOOKING at may be putting up another 3 x 7 element yagi's, But I would like to make a mobile EME syestem on a 4 wheel drive truck as I have a much better location on the 50 acars & much higher, I will look out for may be a truck with a cherry picker on it watch this space you never know what I will come up with.

This is the View from the best spot on my place, Not Bad Hay, LOOKING north east were the MOON comes up about 80 to 90 deg 

 

The old Trusty 2 x 7 elements yagi's stacked 5/8 wave 12ft apart on 6 meter band built in 1990

This is my old and trusty 6 meter 2 x 7elements horizontal yagi's spacing 5/8 wave 12ft apart gain 9.69dBd plus stacking gain. I built them back in 1990 and used in 2 qth's the BOOM is 9.8 meters feed with a 2 way 1/4 wave splitter and a SSB masthead pre amp at the bottom of the splitter, I have worked all my DX with this antenna  stack every one say's that it put's out a BIG signel.

I have been testing it with the new 3 x 7 element vertical stack, the new stack dose not have a pre amp and it LOOK's as the new stack is as good as the 2 x 7 with pre amp but only time will tell, The new system I will be able to elevate the antenna's up to 60 deg elevation for EME.

 

 

Photo of my VHF/UHF array 4x10el 2 mts yagis, 4x19el 70cm yagis, 4x49el 23cm yagis

with elavation, all have SSB masthead preamps mounted at the power dividers

I have just installed another tower. To install 3x6el yagis for 6 meter band EME with vertical polarization & elavation, BUT I HAVE NOW BUILT 3X7EL YAGIS INSTEAD.

 

Another BIG Project underway

I have been talking about building a 40 Meter 3 element full size mono band yagi for a few years, well it is well under construction the \photo shows the H/B element mounting brackets they are made out of alum channel 100mm x 50mm x 3mm.

I am just finishing the elements now, The boom is 15.480 metes long 60mm Dia x 3mm wall, I have to splice the boom together 2 x  6.500 meters long with a 2.480 meter length spliced together at the center It will have 2 hangers either side to support the boom, I will supply more info.   

 

The elements for the 40 meter yagi there is only the center section with one section installed it is 10 meters long with 3 more sections to be installed either end to make up the 20.9798 meters for the reflector. I have to run the program to get the correct length with the tapering and mounting plate . 

 

I have not worked out how I can operate mobile in the pool!YET

Rob at the age 69, Starts the Swimming season 2015/16, I start with a 1.122kms 34 laps of a 33 meter pool, I swim an extra 2 laps every swim, It's ok until you get up to 70 plus laps and after that it's a bit boring. Last season I swam 34.587kms in 20 swims, I will see if I can better that this season. I also Cycle every other day staring at 35kms or Run 10kms

Rob on 04/08/2015 on his Maiden outing Pedestrian Mobile in mid winter in his snow suit & boot's, I have not finished the setup yet. I worked Peter G2YT for about 30 + min while I was walking around the 50 acares on 50 watts with 5/2 signal I went down to 5 watts and received 4/1 report, Peter said he had never heard a Pedestrian mobile so far inland the signal was so steddy Peter was 5/9 all the time. I was going to build a trolly for Pedestrian mobile, but being out in the country with the rough terain the Bicycle cart is ideal with the 20 inch wheels they go over all the rough land and, PLUS I have had it laying around, all I had to do is put a long handle on.

My Home made Crane + step ladder it's attached to the 3 point linkage, the ladder is a 6 meter attached to the post hole digger mount and a very heavy steel pole, you can see what I have to do, to get to some of the antenna's drive it onto a heavy ramp.

I have got my self a much longer ladder it extends to 12 meters I only have to make it fit the the system I use now, I will have to get a parashot just incase!

Thank you for looking me up on QRZ.Com.

I have been active on the amateur bands for over 31 years. My main interest has been the 6-meter band. Since moving to my new location 90 km north of Melbourne. It is a perfect radio spot, I an on 50acres of rural land UP 800mts elevation with no noise, the only problem that I can find is I hear every station that calls but many can't hear me but It looks like that I will have to put up with It Ha Ha! I am now active on 10 meters SSB, My equipment is ICOM IC-746 + Amp running 400 watts with a home brew 2x7 element 13.5 meter long boom mono band yagi.
