Topband: Inverted L improvements - Part 3 (now with data)

[Tim Shoppa]

Todd, have you been tracking your antenna system's performance using
reversebeacon after your sunset?

I'm guessing that your sunset is circa 0300Z.

Last night (Jan 24) you were picked up at 9 western skimmers, perhaps the
furthest ones from you being WB6BEE and the VE6's.

Based on my experience, that this would be expected performance for a good
160M transmit antenna at 5W level on a quiet night. (I certainly don't have
a TX 4-square but I've been in top 10 of several 160M contests). As a
cross-comparison on Tuesday night I was CQ'ing at 5W in the NAQCC 160M
Sprint from my W3 location, and I was picked up by skimmers all over the
east coast and by a few in 9-land and 0-land.

Now a small skimmer data set is not the best way in the world to get
absolute antenna performance results. But with some caveats, A/B
comparisons (using same receiver site at nearby times and frequencies) are
possible between two of your own antennas, or between your station and a
nearby station.
