Hi,

I'm moving to a new urban QTH in and trying to figure out the best HF
antenna installation.

I'd like to have distinct HF antennas for RX and TX: a vertical for TX
where only performance matters and "something" for RX where the main
problem is going to be tons and tons of local QRM.

I don't know what could be this "something". I'd probably like some
kind of loop or small dipole or whatever I can point and can be
isolated as much as possible from local noise received in the
supporting mast and feed line themselves. It should be something
physically small because of neighbors, etc.

I'd prefer to build them myself but would buy them if something seemed
interesting enough.

Feedline is going to be about 100 ft long

What would be your suggestion?

Thanks


Toni,
If you want separate antennas, (aerials), and IF you have the room,
(hence the 100 ft feed line), and IF you want to build the thing your
self. . . Might I suggest for your receiver, a Caged Dipole? In the
more modern world, it is referred to as a Fat Conductor Antenna. I
asked a little bit about them here, and found out a lot more than I
thought I would have, being that these are just about extinct. They
offer many possibilities for what I believe you are looking for in a
receive end application.
