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?
Many 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.
