With 60 feet vertical, getting "pure" vertical polarization just won't make
any difference. Always go for the efficiency. Many people have outstanding
signals with inverted L's.
And as always, worrying about the wire above doesn't matter a hill of beans
if the counterpoise/radial field is not in

Hi,

Dear Topband Aficionados -
I could use a little help. I am currently using a 60 foot base loaded
vertical, with an 8" diameter coil made of copper tubing. I know top
loading gives much better efficiency. The problem is, my lot won't allow
the two top loading wires to be in the same plane, so t
I got some reactions on my message earlier this week I posted to this
group about 160m allocations. Most of the messages noted that the info
was not complete.
Please check
http://wiki.contesting.com/index.php/160m_frequency_allocations and if
you find something is wrong let me know.
What would
Over the years I have developed my own criteria for what constitutes
a valid contact:
1. I MUST copy the call of the DX station off the air. Not from packet
or a chat room.
2. I MUST copy my signal report off air.
3. I MUST hear the DX station roger my report.
I will admit to slippage on it
I draw the line at claiming a contact when either did not actually get it
over the air.
I draw the line at using non-over-the-air to "fix" a log, whether contest or
DXCC credit.
It is clear that there is still magic in talking to VP8ORK running 100 watts
on 160 meters. I looked at their on-line l

I know it's a different answer... but
Be careful about RF coming back in on the RX antenna to the radio, Some
radios have issues with even quite low levels (~100mW) comiing in the RX
antenna port.
the internal isolation may on the face of it appear good enough but any
residual leakage is occurri

I have observed that many of these "confirmations" are made during the
contact. I often wonder exactly how and on which band the QSO was made.

If you model the RX antennas with the TX antennas in the model, and then
without, you can see the change in RX pattern, usually with the loss of deep
nulls. Some situations you can get extreme interactions and reversal of
pattern or loss of any directionality. Better to model with your
dimensions
