Thanks Tony,
I am using an old Yaesu, FT747...it is only one antenna connector on that
radio, so, i have to do a circuit for switching RX and TX antennas and also
a preamplifier for the flag antenna...right???

Hi Douglas,
I use Flag and Pennant antennas. The most room OI have for a beverage is
300'. The Flag and Pennants were always better. Tried Ewe's, but they are
ground dependent.
1000 ohm should be close enough.
If the receive antenna is close to the transmit antenna you may need to have
a signal limiter on the receive input. Or maybe a fast acting relay to
ground the receive antenna when transmitting.

Hi,
I will install a vertical antenna for TX on 160, 80 and 40m.
I want build a Receiving antenna for those Low Bands.
I live in a city lot, so, i can not install beverages...i have been reading
in the Low Band Dxing about Receiving Loops and i like the Rectangular loop
developed by EA3VY and K6SE.
Anyway, i would like hear your ideas.
The Termination Resistor is 950 ohms in the design but i have 1000 carbon
resistor...any idea??
Thanks,
73....Douglas, CO8DM
