Hi guys,
I have a fixed 10 element VHF Yagi pointing at Ohau, which is 160 miles
across open ocean. I can usually hit the repeaters there, but many times
the propagation changes in seconds, as indicated by my S meter which
wavers.
I now have a tower with a rotor and would like to put a second identical
Yagi above the HF beam. My intention is to have a VHF beam that is
rotatable, as well as, to get some extra power and phase separation when
they are pointing in the same direction.
Here is the situation: The beams will be about 20 feet apart in
distance and 10 feet in height. The coax lengths will be different and
each has a different velocity factor.
Cushcraft has said to use their stacking harness at the rig end of the
coax and my system should work fine. I question this arrangement.
Your comments please.
73, Aloha
