Hi
I have up a pair of Jaybeam MBM48/70 multi-beams which I intend to put up for 70cm DATV, but have no tech info on these antennae.
Anyone any idea of the coax lenght's required to make a phasing harness
Regards
Col

There is another way, using a power splitter. I use one here and brought mine on E-Bay from a supplier in Greece. By using a power splitter, you only need to know stacking distance and equal lengths of 50 ohm coax, easier than making up a phasing harness.

I thought that was all I needed to know for a phasing harness, the stacking distance, length of coax's, (75ohm), to the tee socket
