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
