It's a bit late for Christmas puzzles but try this one: Circuit A is the usual antenna tuning cct for a short highly reactive whip. It has the advantage that the antenna tuning inductor can be a long
Dear Walter, I have seen your contribution rather late, because I have been travelling. My opinion is that circuit A allows tuning the whip to resonance and matching it to the amplifier, by changing
Hi J, I must agree with Mike (below) as my vertical wire is about 5 feet from the grounded mast & I have no problems with SWR or tuning etc. May be you need to check for a break in the vertical as Br
I am not convinced that this is the answer. My vertical wire is a few feet from my mast (admitedly a 2in pole, not a tower) and I have had no problems. It worked best with the pole earthed as it then
You might try un grounding the tower and tieing it to the antenna feed point. The grounded tower may be confusing the tuning so give that a try. 73 Bob W1XP
The tower is grounded at its base at this time, but is up on insulators and can be ungrounded easily by disconnecting a 1/0 grounding conductor. The vertical portion of the antenna is a piece of coax
Mike and All, The reason the tower has been bonded to ground is that the tower supports HF antennas as well. The feed lines, rotor cable, and remote antenna relay control cable would need to be decou
Thanks, Jim and Group. Jim's idea to try wiring the Variometer in parallel and see if I have any indication of better things is the first on my list. I am off to the salt mines. Be back in 10 hours.
Jay, Scott, Steve and All, Thanks for the note. The Variometer is built with two coils in both the stationary and rotory windings. Each of these have a one inch space between the coils to allow for t
Steve, Scott, and All, Last night, I was following a thread of another person and their problems with SWR detection in the presence of a nearby strong LF transmitter. It did not dawn on me until this
