As in ARRL literature, even as short antenna in a great ground plane can be
very effective. The Baker Island group has indicated that they were going
to use the salt water..

Hi Ash,
Propagation is very poor and noise is high this particular period of time.
Your Beverage is probably OK.

A good reference for Beverage antenna length is by W3LPL, Search online for
his patterns, F/Binfo.
If a shorter Beverage wire length is used because of space restrictions,a
near perfect feed and restive termination can appear as a low VSWR, over
a reasonable frequency range.

AM radio stations did and still do have to meet field strength readings at

Directional antennas had to be carefully maintained. to protect stations
operating on the same frequency at some distance. Radials on the

Good information.
Finding the best BOG F/B.
I use an model MFJ-5014 white noise generator off the 'back' of the BOG
antenna. Then tune the receiver to find the 'minimum noise' signal frequency.
Adjust the BOG antenna length to bring it into 160 meters..
Care must be taken not to create

Its mostly about doing what you can with what you have with local conditions
that exist.
WD-1A is very strong , difficult to see, and the loss is not all that bad, so
it can be a good choice sometimes.

Sometimes someone will get lucky and get excellent 160 meter transmitting and
receiving the first try.
But most have to work at it with isolated directional receiving antenna (s),
and transmitting antenna(s)
de-tuned while receiving. A antenna modeling program also helps.

Unlike raised radials or a counterpoise...however,.
Its better if the radials, if only a few, under ground are not resonant as the
high impedance/ high voltage end can loose a lots of energy to ground.
It is quite well known that a 'fat' (large diameter) antenna is lower Q, is
wider

Both types become quite reliable when assembled with a high degree of care.
Large temperature variations/freezing can be a problem.

The ARRL took a survey and found that 1.802.5 MHZ would be the
least problem to DX, and USA users.
Many countries can only use the lower part of the band, that goes all the way
up to 2 MHZ.
for the USA.
Hope we can all give each other a little space to enjoy the gentleman's band.
Thanks,

I wish John Devoldere would come out with another, updated "Low-Band DXing"
