[Premium-Rx] Broad Bandwidth HF RX Antenna

[Gary Geissinger]

I agree that the B&W broadband folded dipole is a good antenna for general
use.

Along with the B&W I use a Sony active antenna and a random wire /
auto-tuner combination.  The B&W consistently has lower noise.

As with most broadband antennas, it is somewhat better on some frequencies
than others.

I recommend that you invest in a good low pass filter for it.  I had some
problems with high levels of pager / business band signals getting into my
equipment before I put on a LPF.  At the present time I am using a filter
that only passes 1.5 - 30 MHz that I got off Ebay.  It also helps keep some
BCB signals out of the shack.

The B&W BBFD is a good choice. I use one for MARS and SHARES and have had
very good results on TX as well as RX. It's not as good as a resonant dipole
at a chosen freq but as soon as you tune off the dipole resonance the B&W
performs much better. I also use it on our voice nets and have no problem
being heard when I am the NCS and cover the Mid-Atlantic, New England, and
out to MI.

I like it for ALE and for scanning BBS as you don't need to run an antenna
tuner which for the most part are to slow to tune.

I am looking for ideas on a wide bandwidth HF RX antenna for use with my
premium receivers. Presently I have a 120ft dipole fed with openwire line
about 80ft in elevation being fed with an antenna tuner. The present antenna
is fine for my ham radio transmitting requirements but is not adequate for
band cruising, I don't want to have to be readjusting the antenna tuner all
the time. I don't have a very big lot but do border on a large amount of
conservation land. Rhombics, discones and other huge antennas are out of the
question but Beverage and othe long wire antennas are possible. I have been
also looking into the T2FD antenna and terminated transmission line antennas
as well. I would like to find an antenna that presents a reasonably
nonreactive 50 Ohm load from 2 - 30 MHz, is reasonably efficient and has a
broad antenna pattern, using a balun to do impedance transformations is not
a problem for me either. I would be interested to hear your ideas and what
some of you are using.
