Paul OH3LWR:

While you definitely need the lowest noise figure and a high gain when
using small magnetic loops, I very much doubt that you are going to
need the strong signal handling capabilities for these antennas. Why
not use a dedicated preamplifier constantly attached to these
antennas, possibly with some protection circuitry to avoid damage when
transmitting through your nearby transmitter antenna ?


The idea is to have one preamp or RF stage for whole range of antennas 160 -10
or 6 m. No outboard boxes, preamps, but one good "in house" adjustable gain
amp. No step or switchable attenuators either. Normal city mortals have high
band noise levels, but when you go to the ocean front, use RX antennas or beam
north on high bands, you need sensitivity and of course high dynamic range for
the other end of the signals spectrum, like operating in Multi/multi
environment.

Thanks for N6NWP article info, I will look it up.
