[K3PZN-List] Two monobanders on the same tower

[Benjamin Horton]

Years ago ( Back in the Seventies) We set up  a 10 over 15 meter pair of three element antennas.  I do remember some separation issues associated with the lash-up.  If memory serves me correctly, I think we settled out with a bit over ten (10) feet of separation as the magic number. Did this down at my father-in-law's house on Rehobeth Bay and it did work well finally.  Took us about three months to get it right but it put out a really decent signal.  We finally settled on a single three element Yagi on 20, 15 and 10 meters for simplicity.  After a couple of cable harness issues and some matching stubs we got it right on the single element antennas.  They will work....just hafta have a bit of patience.  Regards, Joe  --  K3FPE

If I mounted two monoband yagis on the same mast separated by about 4 feet, will one affect the pattern of the other and will there be other interactions?   I’m thinking of putting two 3-element Hy-Gain Long Johns, one 15 meter and one 10 meter, on the same mast.  And then later, as we near the solar minimum, switching out the 10 meter and installing a 20 meter Long John.

Just thinking.  I still have Willie Mike’s A4S to refurbish.  Or, maybe pick up a Moseley TA-63-N that covers 20 thru 6..
