I use a plastic container from the grocery store that is a Tupperware knock off. They are small with tight fitting lids and cost about a dollar or two. I run the leads through a hole in each side. Si
I have measured the resistance using the ground rod at the near end and disconnecting the transformer. All you have to do is subtract the termination resistance. Mine was in the thousands of ohms...
Earl: I have had good success by setting the terminating resistance for lowest SWR. This also gives the flattest response over frequency. Would this be the same result as you have described? Chuck, W
This might be a good opportunity for me to give my limited experience with bi vs uni directional short (400 feet) beverage in Stew Perry. I put up a 400' SE beverage just before the test. I had vario
I think you have no filters in the rig on AM. The broad selectivity brings in lots of noise. My S-Meter reads about S-8 to 9 all the time on AM or SSB. Chuck, W5PR -- FAQ on WWW: http://www.contestin
I just put up a new SE beverage and need to guess at the termination. It is only 400 feet long and averages about 12 feet high. I am guessing 800 ohms. I tried it last night on 75 meters with no term
Where can I find a web site or program that I can feed my coordinates and those of the distant AM station and get the direction to it? Chuck, W5PR -- FAQ on WWW: http://www.contesting.com/FAQ/topband
Should I be able to use my beverage transformers with a pennant? What do I do to change them for 75 ohm to 900 ohms? Or should I wind a new balun? Is there a way to search the archives for this info?
thunder I agree with Allen. I have shunt fed several towers and they all worked extremely well. Plus, it is better when you have antennas on the tower with feed lines that have to bridge the gap at
Tape a wire along the mast to the bottom of the tower to ground. Chuck W5PR Hello all, I want to shunt fed my 3-sections Westtower on 160m. The mast is additionally painted with zinc colour and I may
I worked Australia on 160 meters with an ordinary 160 meter dipole no more than 30 feet off the ground using an old HRO-5 receiver and old Globe King 400 transmitter. What does that qualify me for? O
I think I have too high ground conductivity... It did not work well here. I have old river bottom soil. Chuck W5PR I've always used BOGs at 4X4NJ and had 5 of them last year. They work remarkably wel
Do you put the turns on the opposite sides of the core? Hi John, Two turns on the primary and 8 or 9 turns on the secondary. 9 turns will give you roughly 1012 for the secondary impedance. Eight turn
I have protected preamps in several ways. Protecting receiving devices against transmitted power: 1. With most new rigs you have separate receive antenna inputs which automatically protect what is co
Wow! Great web page on your vertical! Thanks for sharing this with us, Larry. Chuck W5PR _______________________________________________ Topband mailing list Topband@contesting.com http://lists.cont
I found that my balloon built static and caused noise in the receiver unless I had about 50 feet of line between the top of the vertical and the balloon. I used insulated wire to minimize charging. I
