If there is any sort of relay box in the line, you might try "hot switching" the relay with 50 watts or so. Chuck W5PR _______________________________________________ ________________________________

I always thought the 468/f was for dipoles supported at the ends due to "end effect" Using 492/f gets you closer, but disregards the effect of the diameter of the tubing. Adjusting for that probably
I have been following this thread closely because I am planning a 4 square and thinking of the single, elevated radial from each vertical. For 160m I was thinking of a quarter wave radial from the bo
I dont see how putting antennas on the opposite side of the mast does anything. They are still connected to the same mast and exerting forces in the same direction according to the wind resistance on
Most surveys in the last few years should be correct. Have you tried shooting a magnetic azimuth down a lot line to see if it is different by about 16 degrees? Chuck W5PR ____________________________
I was wondering the same thing. Im surprised that no amp company makes an amp to go at the tower. Maybe remote a rig and amp close to the towers? Chuck W5PR __________________________________________
I am certain that, in a contest with over 1,000 contacts, one db would make a noticeable difference. I seem to remember some tests like that, but I agree it would be difficult to make valid compariso
Im not sure what AC coupling the feed line is. Chuck W5PR _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.c
It is usually contained in whatever Yagi design program I use such as YO. I think there are stand-alone programs to create a taper schedule, but I didnt find one in a quick search. Chuck W5PR _______
Wont need a tuner if the wire is cut to a quarter wavelength on 80. This is called a Half-Sloper or Quarter Wave sloper. Should be plenty of information about them online. Great DX antenna. Chuck W5P
Grant, where is the series capacitor, before the un-un or between it and the antenna? Chuck W5PR _______________________________________________ _______________________________________________ TowerT
By the way, your local soil map can be found at: https://websoilsurvey.sc.egov.usda.gov/App/HomePage.htm Probably not very accurate, but a good approximation. Chuck W5PR _____________________________
Thanks for the info. I think I am going with 60 radials on the ground. I want to use the 160 vertical tower to support an 80 meter array around it. Elevated radials might make adjustments way more co
I understand many (all?) of the newer houses have insulation with aluminum foil backing inside the roof. My friends who have HOA restrictions, put antennas on their wood fences. Nowadays with modes l
There are side-mounts for towers that might be adapted to fit your mast they have a shelf for the rotator and another shelf with a bearing for a mast above the rotator. This would remove the strain f
Am I correct in assuming that Beverage wires sloping downward from the feed point to the termination will work better than ones that slope upward? I have two places I would like to put bidirectional
Thank you everyone who replied. The consensus was that sloping ground will not matter much. I was discussing with Tree that I may have the opportunity to put up a similar, same direction, but tempora
