Anything I need to know about setting a tower base in south Florida? I am currently in central Texas but if I move to Florida I wonder how different I will find soil, ground conductivity etc? wb5oxq

I must move my 40 and 75 dipoles due to rfi in the house that I cannot resolve. I am thinking about 1 dipole fed with ladder line or window line. I have 2 possable support points. 1 pair is 126' from

Thanks for the opinions so far. Currently I have a separate dipole for 75 and 40 meters. Both center insulators are on a bracket 52' above ground and on the same tower with the tv and fm broadcast an

Thanks to all who answered my question about this antenna. I ordered a kit from DX Engineering with 135' of wire and 100' of window line. This might not be the best but at 49.95 How wrong can you get

I have a Force 12 C-3 beam with a 5kw DX Engineering balun and rg 213 cable. everything works well on 20, swr is low and tube amp loads properly. On 15 swr is a little higher about 1.6-1 but the amp

I may be moving from Central Texas to South Florida. I currently have 2 50' towers which I will not take. I would like to have a good hf beam and probably a wire dipole for 160-40 if I have at least

When I do move to south Florida and if I have to use a wire antenna for all bands which would be better considering plentyfull tall trees what are the pros or cons of using an inverted L, a half wave

I have what is reported to be a good legal limit tuner that I use with an 80 meter dipole fed with window line. Dentron model MT-3000A. It will even tune the beam to work on 6 but too poorly to hear
For the lower hf bands especially would a full wave loop work better horizontally on 4 60' towers or vertically on 2 60' towers with the top of the loop at 60' and the lower part at 40' or 30'? For m

When choosing a height for a beam is 1/4 wave above ground at the lowest frequency enough? 1/2 wave? I see Force 12 rating the gain on their beams at 74'1". Why that height? At 20 meters is 100' a lo

I have a full size 80 meter dipole at 60' in the center fed with 300 ohm window line to a good tuner with the balanced input. I cannot use it on 80 or 40 meters even at levels of 25 watts or more bec

I am considering trying the 120' qso king end fed antenna for multiband use. I really dont needed it on 20,15, or 10. Maybe 6? I have a 50' 25g with a triband beam on top and a 30' 25g 128' away. Thi

OK I may try one. I will also buy the recommended line isolater to m ake sure no rf backs up into the shack. I have a 80 meter dipole fed with 300 ohm ladder line into the tuner and it seems to work

I ordered one. Now, he says u need at least 50' of coax, more is ok. He also say you need some kind of choke so rf does not get in the shack. Where does the choke go? On my beam the choke goes at the

This is way off subject of antennas and towers. Using wooden clothes pins reminds of many years ago, in the early years of Ultra Light Aircraft. Living/working in the SF Bay Area at the time, one wee

I just want to let you know how well my antenna works. I compare it to my other wire antenna a 135' doublet fed with 300 ohm window line intlo a Dentron MT3000A tuner. The dipole center is 55' and th

Actually in my configuration it resembles an inverted L with a matching network at the top corner of the L Sounds similar to a Carolina Windom (off center fed dipole sold by the Radio Works). - Mike
