I forgot to mention that the MBM88 was also referenced as a Jaybeam. It was manufactured by Jaybeam Limited, ,Northampton, England and was recognized for its excellent performance.

I have an MBM88/70cm antenna that was very popular several years ago. Is anyone currently using it on satellite reception? I want to tune it for 439.25 MHz. Does anyone have a procedure for tuning to reduce SWR ? Specifically can the wing nuts on the reflector and director be loosened to slightly move the element position to optimize SWR? Anyone with experience of coax length that might effect SWR? Any references or suggestions would be most appreciated. Pleases reply off line. Thanks, Farrell Winder, W8ZCF Cincinnati, Ohio, USA
