Times change.
In recent years vertically polarized man-made electrical noise has been a
growing problem. I was forced to use a dedicated receive antenna to
mitigate severe local noise problems (switching power supplies, plasma TVs
etc.) from my surrounding neighbors. Because the only practical

I’ve used small tuned loops to null out local noise and various wire antennas.
The biggest issue I’ve had with receiving antennas has been trying to keep the
transmitted power out of the transceiver’s separate receive input. FYI, a pair
of parallel crossed 1N914 diodes across the input worked we

when I transmitted on my dedicated transmit antenna, I fried the front
end of my receiver. Won't do that again. Of course I was a green

Before I could afford a DowKey I used a DPDT knife switch with my AT1 and
BC348. This was in 1957. I have never used a separate receiver antenna either.

I suppose that if you're writing a book that has receiving antenna in its title,
you're going to have to make a case for them even if you have to stretch a bit.
I remember bolting a 115 VAC coil Dowkey relay on the back of my DX100 for
antenna change over in 1960 or so. It was several years be

The ARRL recently published a book “Receiving Antennas for the Radio Amateur”.
It maintains that “The function of transmitting antennas is to radiate power
efficiently, while the function of receiving antennas is to present the best
signal-to-noise ratio to the receiver”. It maintains that “usin
I truly do not understand why this idea that "I can work anything I can

meaningless reference. Antennas are generally (as in almost always)
reciprocal between transmit and receive, so if you suck on transmit

Some window screens are aluminum. I've used aluminum screen
successfully for the ground plane for a 10M vertical antenna.

Tom and all,
One of the KX2 Field Testers found that a 58 foot resonator and a 26

I use half those lengths for 40 through 10 meters.
No feedline, both the radiator and the counterpoise are connected
directly to a BNC to Binding Post adapte
This is probably NOT what you are looking for but it's about random

Hello,
I want to re-read a post that Wayne n6kr made about a wire-antenna tossed up a
tree and the location of a counterpoise; this was relative to portable

But my archive search has come up empty.
My recollection is he recommended placing the
