Try an AEA VIA Echo. A lot more than the MFJ but worth it.

> Hello group, after finally getting my SSB part of the station fully operational, I then moved on to getting my packet operations up and running , and with great success, one wee problem, I have noticed this when tracking the ISS, I am able to still digipeat off the station even long after it is supposed to be beyond the horizon according to my Satpc32 ISS software. My keps are up to date via the Satpc32 software, is there a error due to the large amount of mass now docked on the ISS? or have the keps not be uploaded in a timely fashion to the server I get my keps from?...

Indeed, it reads 1.1:1 at UHF and that is just fine for my measurements. Rarely do I see an antenna match less than 1.1:1.
