Pete N4ZR suggested I put this out to the group:
I would like to hear from skimmer ops on what ANT systems they are using for
I am in the SW corner of the US, on the wrong (west) side of close-by Mt.
Soledad and have roof space-limited ANTs. I use a PA0RDT active mini-whip ANT
about 5 ft above my roof for my SDR-IQ radio which feeds the skimmer. I was
surprised to see from N6TV's RBN stats that I have the lowest SNR average for
signals of reported RBN skimmers, and post only 1/5 the spots N6TV had and 1/10
the spots WA7LNW had from my part of the country.
I have tried putting my 2-el Steppir yagi pointed 045T on the skimmer when I am
not contesting, and even that little extra gain results in more skimmer spots
from NA and EU. My plan now is to find a used A3 tri-bander that I can cut down
to a 2-el due to space limitations and because I want a broad beam width. I plan
to use a coupler to feed both the active mini-whip and the 2-el yagi to the
skimmer's feedline, so I don't have to mechanically switch ANTs when SkimScan
switches to the low bands at night.
Anyway, I would be interested in what SDR or other radio you use, and what
ANT(s) you use for your skimmers.
