Took down a set of DB212-3 dipoles in good shape with harness. I want to use
them on 6m for a repeater antenna. I also want to add one additional dipole.
I guess I will need to modify the harness and the dipoles as they are marked

I'd suggest using four if you have the tower real estate.
Adjust each element individually on the tower up in the clear (not
necessarily in the final location, but away from obstructions).
I don't know how the harness was designed for three elements, but making one
for four is easy. Each
mastr II for the
task now.

In a previous life I managed the communications for a state police agency. We
used 45 MHz for our main system and had forty some odd tower sites, almost all
running DB212-3 antennas.
Two of the sites were on 1000+ towers and used a single DB-212 element due to
the large tower face and the

if there's enough tower.

I'm glad somebody brought this up.
I've got 2 of the DB212 antennas, without any phasing harness.
The tower that the repeater is going up on is 90', wide spaced triangular
tower (about 20' at the bottom 8' at the top).
I'm just wondering if the work in building the harness, building the

Do you know how the phasing harness was constructed for the three-element
version? I don't, and that's why I suggested to Norm that he go with four -
the phasing harness is easy.
Or, he could use two elements

The radio I'm using in the mobile is a GE Orion with a noise blanker.
However, a noise blanker is designed to help with impulse-type noise.
Microprocessor hash and similar noise sources are continuous, so I doubt a
blanker is very effective
