Hi Tony
Use the same antenna for both TX/TX. This is what I
do at my QTH and if works very well. On RX some control over gain would be
convenient to set the optimum front end RX gain. ie an adjustable attenuator. It
also depends on the RX in use. A vy sensitive RX would probably need attenuation
whereas a poor RX needs plenty of antenna gain.
The ic - 706 works fb with a big antenna but vy
poor on short antennas. I have several receivers and they are all different on
LF and MF
Separate antennas for RX are ok if you have
plenty of space to keep them away from the influence of the main Antenna.
On RX a large antenna has the advantage of plenty
of capture area for weak signals without preamps and related
complications.
I am QRV every day on 137.7 and await a call
from you, also active daily on 502.5 Kcs. CW and QRS3.
Its a long time since our last CW qso

Subject: LF: Separate Receiving
Antenna?
Soon I may use a freestanding and isolated 125m mast with an
excellent radial network for LF. Should I use a separate receiving antenna or
try to receive also with the mast?
