The MM-1 is a dual ratio UN-UN (unbalanced to unbalanced transformer).
Great for coupling your 50 Ohm coax to an antenna with a feed point impedance of
either 25 or 12.5 Ohms, typically found in a mobile environment. Ideal for
antennas that have been enhanced with a Hot Rodz
Capacity Hat.
Unit is housed in an aluminum enclosure and uses silver/teflon SO-239
connectors.
MM-1 Power handling capability depends on the
match:
Using the 25 Ohm to 50 Ohm port, with SWR below 2:1 on
the 50-ohm side, -- 750 watts PEP
Using the 12.5 Ohm to 50 Ohm port, with SWR below 2:1 on the 50-ohm side, --
500 watts PEP
