I would like some advice of using my crank up US Tower pole as an antenna
for 160. The pole is mounted on top of a concrete block that has 4 threaded
iron rods on which the pole is set . the block is 5 feet deep.
Does the concrete block insulate the pole from ground?

Please help me and some other topbanders in the Eastern Caribbean and SA to
try and beg 3D2R to come up to 1822 a bit earlier than past our sunset.
There is a huge difference between East Coast SR and my
not conduct well. If it is not possible to drive a rod all the way in, avoid
leaving a large amount above the ground. (Short metal lengths can pick up
signals like AM car radio antennas did years ago)
Carl and all,
For safety reasons ground rods should NOT stick out of the ground. If one
If anyone is in need of Teflon Tubing, I have some in #11 and #12 size. That
is the inside diameter.
If someone needs some, I will give you a good bargain. 5 feet for US$10.00

Please contact me at w0ri...@sbcglobal.net for the details.
Phase noise is generated by the rig's LO and exists as a more broad band low
level signal. Issue is more significant with modern day DDS than with older
analog-type VFO sources. Guys who operate field day can relate...

Don't you mean IMD from the radio/amp driven past ALC?

Paul, I will agree with Lee. I think the best would be to use a small relay
that would open the antenna on transmit and also short it to GND. Nothing
touching the Pre-Amp.
All Electronics have some very nice DIP relays that will do the job. I have

Perhaps, bu they also sell junk connectors, so I wouldn't trust them unless
they were Amphenols in Amphenol packaging.. I know -- I bought some really
junky DINs from them, and when I complained, all I got was hams are cheap.
