After reading many review of the Isotron antennas (the ones which look
like birdfeeders!) I had bought a 40 meter version as well as the
10/15/20 combo.

Put the 40 meter version up on a 12 foot mast, super easy to tune,
worked great, 1.2:1 SWR across the 40 Meter CW portion of the band
without the use of a tuner. Made better 40 meter CW contacts on the
Isotron than on my dipole, I still can't believe how good that
"birdfeeder" works.

Well I'm putting the 10/15/20 combo version together and its been more
of a problem. Can't get a good SWR, about 2:1 is the very best I can do
on any of the bands.

Each antenna has an SO259 connector and each antenna is connected in
parallel via short piece of twinlead. So I don't know which antenna I
really should connect my coax to, the 10, 15, or 20? Anyone have
experice with the 10/15/20 combo who can offer some suggestions....
