Review on 📡 Professional 1/4 Wave GP FM Broadcast Antenna for 87-108MHZ FM Transmitter with 15M TNC Cable - Suitable for 0.5W, 1W, 5W, 7W, 10W, 15W, 20W, 30W, 50W, 80W, 100W FM Transmitter by Justin Vasquez

Antenna did not come with instructions but if you look closely at the black emitters the frequency is marked. The buyer has been in the electronics business for over 50 years and this experience was not required to assemble and install the antenna. After connecting the antenna to the transmitter and checking the SWR I was very pleased to see an SWR of 1.1. Be careful and make sure the coax end connection on the transmitter is correct as you will need a TNC male to BNC male coax adapter. The coaxial cable connector ends with a TNC plug, which means you need a TNC jack that matches your transmitter's connector.
