I might have done that. It was 20 years ago :) From: MrToby <mrtoburen7@gmail.com> Sent: Friday, October 12, 2018 7:11 PM To: Dick Green WC1M <wc1m73@gmail.com> Cc: Guy Olinger K2AV <k2av.guy@gmail.c
You dont have to lower them but you need to short them to ground to make them electrically invisible _________________ Topband Reflector Archives - http://www.contesting.com/_topband
Interesting. This is not how I tuned my 40m 4-square, albeit with tubular elements not slopers. Anyway, my understanding is that you disconnect all four elements from the control box and measure at t
Hello Topbanders, just wish to tell you about my sloper system, I used some years ago on 160. This was installed by me on 160 after hearing of the success of such as system from Roy, ZL4BO and Dave,

Essential point that might be missed: each one of the elements, one at a time, must be tuned independently with the other three elements down. This is the initial tuning. If when everything hooked up
Yes, install ONE sloper. . .measure and cut to resonance. Duplicate that measurement for the other three. 73. . .Dave, W0FLS Terry, I assume you only installed ONE sloper and made your measurements ?
Terry, I assume you only installed ONE sloper and made your measurements ? With all 4 installed there is way to much mutual coupling to get a meaningful reading. If your readings were from only ONE a
Hello Guys and Gals, Recently Tree did some work for me and one of the things was to put up the Comtek 80 meter 4-Square switching unit and a couple of pulley setups for my raising of the 80 meter sl
Not that I ever used one of those, When I was a teenager the "old" hams who were in the signal corp talked about antennas they used in WWII (God bless 'em all). The crow's foot comes from hanging the
I, K3VW, then, WB3GCG of Brandywine, Md. had a pair of phased delta loops on two 150' towers, back in the 70's & 80's. A wire yagi would have taken up more space then I had available at the time. My
Thanks to all for the help. Seems will not work right in my situation. I have plan to rise a 190 ft tower having in mind the Comtek system of four folded slopers, like K3LR use, maybe next year. So t
I'd avoid half slopers and any other kind of slopers. For short and medium distance work you couldn't do better than a simple properly fed Inverted-V dipole. Make the top angle as large as possible,
Greetings from the High Desert! I sure am enjoying my first year of semi-serious DX'ing on Top Band and thus feel the need to make some antenna system improvements. I've been kicking around a few alt
I have two quarter-wave slopers on opposite sides of a 120 ft tower with bonded aluminum on top that lengthens it electrically. The quarter-wave wire are insulated from the top and held about 5 ft fr
Guys I want to model phasing two slopers on my 100ft towers anyone has eznec files for slopers that can facilitate? 73's Felipe _________________ Searchable Archives: http://www.contesting.com/_topba
Hello guys and gals, This last winter season I did not get much out of my 80 meter 4-square. I've tuned it about as well as I can. It is using 1/2 WL slopers, a Comtek 4-square controller and is off

With a grounded tall tower with uninsulated guy wires perhaps the best solution would be to install have wave slopers with at least a 45% angle of declivity and space as far from the guy wires as pos
When we last left this adventure, I was shunt feeding my 110' tower on 160, which supports a multitude of yagis and wires. Unfortunately, I was coupling so much energy into the 80 meter wire array th
Herb's experience below echoes mine at my house here in GA and at BC stations in the Midwest. Others besides Herb have reported the same. I used or tried to use a 308 foot self supporting base insula
