I'm going to order the A148-20T soon. I'm intrigued by with using the phasing harness to R/T with simultaneous dual polarity. It comes with the loss of approximately 3db.

I have two 100' runs of 9913f7 and a quality two position antenna switch. If I go with the harness, I'll only need one feed, but the harness option isn't cheap. I'm not terribly concerned with 3db loss, but it's nice to have it, especially with the the limitations of height and surrounding terrain.

I have a dual band yagi that I plan to use in a fixed configuration. My intention with the A148-20T, is for DX and for whatever I can scare up.

How would YOU feed this antenna. My gut says cophase it. Anyone got one of these?

I have a pair of 13B2 yagis and am trying to decide how to mount them myself. I could go with both horizontal for maximum gain or one on each polarity however I have been toying with the idea of orienting them as an X and phasing them to generate either H or V. The X configuration has the advantage of allowing water droplets to run off and not collect on the H elements as bad which can then freeze and detune the antenna. It is easy to produce any planar polarity as well as circular polarities as well.

Food for thought.

    Hello I have a old school 2950 receives great on all modes and transmits great on AM but no transmit on SSB. Does anyone have any idea?
