November 29th, 2014. UPDATE
When we returned from Galveston, we found out the loop described below had been struck by lightning. No one was in the house at the time. The lightning vaporized part of the ladderline and half the 14 gauge antennna wire, and hit all the ham equipment and most of the electronics. I had disconnected the antenna before we left, but since it was November, didn't think of disconnecting the power from the rigs and power supplies. Luckily I had taken the KX3 with us and so I have a rig to run. Today I put up a 270 ft delta loop fed with ladder line to a 4:1 balun and short run of coax. I'll be running 5-12 watts with the KX3 until the Insurance replaces the stuff I lost.
If you worked me Nov1st thru Nov6th, WB0WQS/5, I was operating portable from Galveston Island, Texas. I was running the KX3 running battery power 5-10 watts.
If you look up at the crows nest, you will see a orange telescoping fiberglass pole, supporting the 31 ft vertical. It is fed with a 9:1 unun and 25 ft run of coax to the deck where the KX3 is set up.
My Home QTH is near Joplin, Missouri.
Please QSL LOTW only.
I had to replace the INV-L with a Horizontal loop. We had a storm blow through and it took down my Inverted-L. The new antenna is a 220 ft Horizontal Delta loop, 65ft high fed with ladder line to a 4:1 balun. The length was determained by the wire that was left on the roll.
I have made many contacts on the loop and I'm happy with it. I'll comment when I have had it up longer. I plotted the antenna on Google earth the best I could (below). The feedpoint is the South East corner fed with ladder line to a 4:1 balun. The three corners are all 50-65 ft above the ground.
The above loop has replaced the Inv-L below.
My prior antenna was an antenna that W4RNL modeled and wrote about: a 135' center fed Inverted-L. One leg was 65 ft horizontal, and the other leg was 65 ft vertical; fed with 400 ohm ladder line. It was fed at the 75 ft level. The late Cebic wrote that the 135' ft Inverted-L has decent gain figures and low take off angles, I decided to put it up and give it a try. I shot the line up there with a compound bow and arrow with fishing line attached.
The photo below is the Inv-L before it came down. The Horizontal wire ran in the 333 degree direction. The antenna was fed at the top. I have highlighted the vertical wire with a thin, black line (look carefully). It ran down to the yard tied off with a short piece of white rope and an insulator. The feedpoint up at the upside-down L was fed with ladder line, it then went to the back of the house to a 4:1 remote balun and a short run of coax to the tuner. I thought I would leave the antenna notes, and photo here as an record of the antenna.
I recently upgraded to a BALUN DESIGNS Dual Core #4115 4:1 Balun, and short run of LMR-240 coax to the tuner., I have also added an Ameritron ALS-600S amplifier, the tuner is an LDG AT-600Pro II, The two work very well together. I call the DX station with 100 watt level several times first, and if that doesn't cut it I kick on the amplifier. Last count is 213 countries worked, and 170 countries confirmed by LoTW. Hope to see you in the pile-ups!
Field Day 2014!
I set up as 1B at a cabin we rented near Joplin. The rig used was a KX3, running 5 watts battery powered with a couple of 12 power stations. The antenna was a 88 ft EDZ up about 45ft in the tree tops. I shot the line up into the trees with a wrist rocket and fish sinker. The land had a second cabin nearby that was rented and the guy came over and said he had to ask me what I was doing. Crazy man shooting fish line over the tree tops.. lol.
Was able to operate about 16 hours of the contest, because thunderstorms chased me inside the cabin a couple of times. I used that time to nap. At 5 watts, the KX3 was able to snag 246 qsos, mostly on CW. We made about 20 contacts on SSB. When I say "we", My 19 year old son Ryan stopped by after his work shift and I offered him the mic. Lots of repeats, but he did pretty good. Worked contacts on 40,20 and 15 meters. The KX3 is amazing. The filtering and audio out of stereo headphones is incredible. Thank you if you worked me during FD 2014. There was some great ops who pulled me out of the noise. Hope you had fun. 73.
