L INVERTED 40/80M with optional 160M (Work 6 to 160M) par FG4NO

(Sorry for my translation :) )

 

After having tested multiple antennas with more or less good results, I have opted for the L inverted and gives you the explanation. It is scheduled for 40 / 80M (160M optional) but works on other bands.

Above all we must take into account my geographic situation that does not give me the right conditions to make some types of antennas. Take into consideration the earth, vegetation, coconut palms, trees, the earth that contains a lot of volcanic rocks, pebbles and not talking about this part of the land is sloping and necessarily in a bowl. There is nothing to help a good antenna and then flush the bowl also to make myself heard over 80M with my G5RV so I have opted for the L inverted. I have to say my brings enormously. She is still in the testing phase and I see something to do, I make changes.

So my construction of the L inverted and of course these values can be changed but given my limited space I took the length of 21.38m which gives an full wave 20M, half wave 40M and quarter wave 80M.

L Inverse FG4NO


I haven that place, to put my antenna and that not necessarily help with the fence, trees etc. I have the problem turns in all directions to find a solution but I see that it currently.


Materials used:


- Fiber Glass Mast 10M HD (Wimo)
- Balun UNUN 4/1 (Dx Engineering)
- Air choke balun (pvc pipe diameter 100 and 25 feet of coax -7.62m- 6mm)
- 30M coax (100 feet)
- 100m (329 feet) H07VK (1.5mm 2)


*******************************

Long wire of 21.38M (10M vertical and rest horizontal)
Radials: 1 80M (21.29m), 1 40m (10.67m), 1 30M (7.41m). Subsequently I have added two radials 1 and 1 21.34m 7.13m


*******************************

Remember that I do with of the earth, I repeat myself but take into account.

Look at my logbook (http://fg4no.net/) the Qso 40M and 80M realized with this antenna and only with 100 watts from the 09.02.2015. I think it is a good start.

If you need to test this antenna, make changes, suggestions let me know.

See you soon on 40M and 80M.
