I have recently been given what appears to be an M^2 circular polarized 2M
antenna. Its configuration is two 6-element yagis mounted 90º to each
other and offset by lambda/4. Each yagi has a dual driven element (two
split dipoles driven out of phase). There is some type of phasing harness
that connects the two dual driven elements that uses two parallel conductors
(~lambda/4 long) coaxially surrounded by a braid shield (I cant read the RG
#) that terminate in a center molded assembly with a single SO-239. The
antenna itself is in excellent condx but the phasing harness has
deteriorated. Can anyone identify this antenna and provide some insight
regarding duplication/replacement of the phasing assembly? (The Ant. Hdbk.
appears to have a number of alternatives.) If required, I can supply
digital photos.
Tks es 73,
