UHF Antenna Divider HT-UK1

HT-UK1

The antenna provides two-in-one style high gain receptivity for the wireless system with UHF 500-900MHz and the receiving band will cover the whole UHF channel. The directive antenna design also provides ideal long range and steady reception for the UHF wireless system
The antenna Distributor is designed for long range reception and transmitting application, such as gymnasium, concert, theater and large performances; or some environment which can be blocked sight and reception, and the antennas can install or remove easily and firmly for convenient portability.
The antenna can be roughly used almost all UHF receivers, also provides 180 degree directed reception among fixed frequency. Compare with the standard antennas addition in the receiver, the antenna distributor promote about 13dB radio frequency signal when the impedance is 50 Ohm.
