Isn't the match used on the Telrex antennas a T-Match?
That would require a 4:1 balun (Telrex used a coaxial 1/2-wave balun).

Quoting James Archer <James.Archer@erm.com>:
Tuning a Telrex 10M523 (Telrex 5 element beam on 23 foot boom)
After several days of work on the ground working with the matching
system and trying multiple combinations of driven element length to
the Telrex match position-the best we can get is an SWR of 2.3 at
28.500. We are using an MFJ tuner through a 4 foot piece of coax to
the antenna. Antenna has a tuned matching stub set for 28.500.
We have followed exactly the specifications from the 5 page Telrex
instructions that are beautifully illustrated.
This is a wonderfully built antenna and we are very keen to get this
tuned up right and in the air working!
Anyone have any golden words of advice, we are of course looking to
get the SWR down below 1.5:1 at 28.500
Thanks in advance for any help you can provide. Replies to N3ZS at
