I need to reduce the transmit power of my PSM transmitter from 100 mW to 50 mW (a loss of 3 dB) in order to comply with new FCC regulations issued in 2010. Is there an external pad that can be used? How about for the UR1 transmitter, too?
Mini-Circuits sells the model HAT 3+. This is a 3 dB pad (attenuator), 50 ohms, 1 Watt power ratio, with BNC connections. Connect the PSM transmitting antenna to the HAT 3+ pad, then connect to the PSM transmitter.
For the Shure UR1 transmitter, use the model VAT 3+; it has SMA connectors to match the UR1 transmitter and UR1 antenna
