Hi John,
Can you tell us a little more about your SO2R setup??
How much power are you running? What BandPass filters are you using, if any??
Are you using stubs??
Many Thanks for any info!!
73,

I have never seen anyone put two SteppIRs on the same mast but the 7 ft
separation is more than adequate for operating on two bands simultaneously.
One of my homebrew 20m beams also has a commercial 40m beam mounted on the
same boom and there is no interference except on the harmonic.

I live on a small lot, 80x180, in a subdivision....I have a 50ft tower
with a 3L Steppir on it.....I had planned on putting another Steppir 2L
about 7 ft above the tribander.....BUT......my current SO2R setup I'm
using a Hytower as the second antenna.....the rigs are a 7610 and
7300.....I have 5B4AGN bandpass filters on both rigs.....I'm already
having interference issues between the rigs now, so I think moving a
second antenna to the same mast is asking for more trouble. Just
wondering if anyone uses 2 antennas on the same mast for SO2R? Also, is
the 7300 maybe a problem? I heard that radio generates a lot of phase
noise on TX, not so good in SO2R applications. Anyway, planning for some
tower maintenance this summer, and looking for suggestions on optimizing
the station for SO2R....
