Topband: Low Dipoles

[Wes]

I have no separate RX antennas here. Still, I believe I have parity between TX 
and RX performance, at least at my 500W power level.

Generally speaking, I think I have a reasonably quiet location and despite 
having two acres, the siting of my house, an existing tower, the TX vertical and 
neighbor's homes (noise sources) I'm left with few to no locations for an RX 
antenna.  Maybe something like a K9AY but that's about it.

Now suppose I install a K9AY with its relatively broad frontal lobe.  From my 
location in the far southwest of the US, the major DX center, EU, is a path over 
the continental land mass of the US. With good nighttime propagation atmospheric 
noise in that direction is propagated as well as signal and a "low-noise" 
antenna offers no improvement, the SNR is set by the path.  The back of such 
antenna is looking at the day lit Pacific Ocean.

At my sunrise, for the most part I'm looking west to NW for DX.  Noise and QRM 
from the east is attenuated by sunshine and I don't need directivity.

So that's my case, again at my power level and location.  My good friend Larry, 
N7DD, might argue with me but he runs a lot more power than I and has room for 
much more directive RX antennas.  As the realtors say, location, location, location.
