Greetings, I've a Butternut HF2V that used to be elevated with the feedpoint at 10 ft. and 2 tuned radials each on 40m and 80m also at 10 ft. I was satisfied with it; it seemed to hear well enough an
If you're going with ground mounted, 12 radials is nowhere near enough, especially on 80 meters. You can probably make 40m work with that setup -- I did -- but you'll be doing your DXing with 3x3 sig
James; Just out of Curiosity, how did you elevate the radials? Ken _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@con
Hi Jim I never tried elevating my HF6V (similar in principle to the 2V), but I'm not surprised by your results. My HF6V worked OK on the high bands, OK on 40 but was little better than a dummy load o

James, I recently installed an HF9V at around 8' AGL. I use 2 elevated "ground"(counterpoise) radials per band, sloping from 8' down to about 5' AGL. I find it works VERY well on 40m and up and adequ
I mounted mine on the ground which used an extensive radial system...leftover from my 160 meter vertical tee-top. The radial system consisted of around 60 130 foot buried radials. I never could get i
I've run several top loaded HF2Vs over two dozen 66 foot radials over water bearing clay and septic leach field the past 27 years at my current QTH. I chase DX on 160 - 80 - 40 and get good results (
Over the summer, I did extensive modeling (NEC) of vertical quarter-wave and vertical dipole antennas, comparing performance on the ground and at typical roof heights. A report on that work is on my
Jim, Are you really measuring what DXers are really after when comparing vertical antennas at different heights above ground and ground mounted.? A DXer is really interested in the signal that leaves
Read the link. My criteria is low angle radiation. 73, Jim K9YC _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contes
I have an HF-2V ground mounted with 32 - 40 foot radials under it. When I went from 16 to 32 radials, 80 became significantly more touchy to tune. That said, it works very well on 40 and 80 into EU.
I have used an HF2V here in southwest Florida for about 7 or 8 years. I ground mounted one with a fair amount of radials, no particular pattern, some long up to 100ft. some short to about 30ft. Total
Hi Jim, Interesting results. At my old QTH, I had a DXE 40/30M vertical with the base mounted at 28¹ on top of my shed with 10 elevated radials. It worked great. Now at my new QTH I have a 90-100¹ hi
I have 4 twelve foot wires as the Top Hat (umbrella) with weed trimmer line as the remainder for guy lines on my HF-2V. The top (40 meter) coil is completely collapsed and shorted out on my HF-2V usi
Mike, I forgot to say the top loading can give your HF-2V a low VSWR across the entire 40 M band or across the entire phone or CW portion.... great for contests! 73 ES DX, Gary -- AB9M --Original Mes
I have a Hy-Gain Hy-Tower on top of an all metal barn. Base is about 23 ft AGL. I have no radials. It works pretty well. I got a recommendation to put at least 4 radials on the roof (2.5:12 pitch gab
As a Novice in 1974 I spent three weeks in a travel trailer with a stainless steal roof testing antennas. I was primarily interested in CW on 80 and 40 meters, but also used 15 and 10 meters for dail
A very interesting question. I've had two verticals on metal roofs but the roofs were galvanized steel over wood frame. Thus the roof acted as an elevated ground plane. One worked very well for me wi
Yes, Grant... Very interesting problem. My building has 10 steel columns, 4 at the corners and 3 along each long wall with one centered and the others equally spaced. These are Ufer grounds, more or
Yesterday I spent the afternoon adding 4 - 12 foot top hat wires to my HF2V. You can see the pics on my flickr feed at http://flic.kr/s/aHsjMzxCt2 Bandwidth on 80 improved from about 25kc's to about
