Nice Dave... Thanks for the effort... Being that I operate primarily 80 and 160 cw it sounds all too familiar, esp. the minus 3 dB...
Confounding the issue on these bands is that highly directive antenna patterns are hard to come by, and are most difficult <and usually too expensive> to improve by 2 or 3 dB... Most of us on 80 meters settle for some limited directivity/gain on transmit and resort to separate receiving antennas for better S/N ratios...
On 160 omnidirectional transmit and separate receive is the norm...
So, usually receive is the area where the 1 dB improvement will pay off...
At my station, a 1 dB improvement will cost about $3K...
