One remote tall (17") antenna (select QTY 2 if you want to remote a pair) Each includes as shown 1 rigid antenna, and 1 magnetic base with 12 ft cable terminated with TNC. Base has removable rubber protective cap over threaded portion. If your wireless receiver is in a rack, or setting at desk level, you may have dropouts due to the rack, or a sea of people absorbing the signal. Remote antennas let you get the antenna up higher over peoples heads, for better pickup, or outside of a metal rack or away from rack wiring which blocks signal. The antenna itself is closer to full wave size rather than the stock 1/4 wave, so you may have some added gain from that aspect as well. Magnetic can stick to top of your metal rack or other metal object For temporary setups, you may be able to stick base to a mic stand or boom arm. Includes a round rubber pad to protect metal, or remove rubber pad for stronger magnetic power. Works with EV RE-2. R300 and Telex FMR450 UHF systems. Note it does not fit the new EV RE-3 series unless you add a TNC to BNC adapter not included, (If you need for RE-3, ask first, we MAY have some adapters in stock) For even more added gain, attach this antenna directly to/over a larger ground plane, which could be anything metal such as a metal rack, a metal plate, or even a drop ceiling grid (you can mount it upside down).
