I have a Shure EC2 wireless microphone
transmitter, operating at 209.000 MHz. The antenna
is a 1/4 wave helical with a female SMA connector,
which Shure no longer supplies. Does anyone
know of a supplier, or a custom house, where
I can buy/commission such an item?
thanks in advance,
I wonder if a 220mhz ham radio antenna would
work well enough for you. Many HT's are comming
with SMA connectors now.
