Iv noticed alot of talk on GMRS forums of people asking about antennas and replies of this antenna will work between 4**Mhz and 470Mhz and never mention that it needs to be tuned. By reading what people post it sounds like people dont know that they have to tune every antenna. You have to trim the antenna to get a SWR below 2.0 or better. 1.5 or lower is ideal. for GMRS you need to tune your antenna at 465.00000Mhz if you use repeaters. if simplex only, 462.60000Mhz. you dont just install a antenna because it list that it works between. 420Mhz and 470Mhz. That means it can be tuned between those channels. you tune at the center of the band you are using. or you can use the channel you will use the most. your frequency range will be the channels you can get below 2.0SWR.
