Gorke AYK-437 BNC directional antenna

AYK-437 is a Yagi directional antenna, 7 elements, supplied with a 3m RG58 cable with a BNC plug.

The antenna has a gain of 11.5 dB and, in accordance with applicable regulations, in When using it for cooperation with transmitters, this principle should be followed not to exceed the permissible radiated power of 10 dBm (EIRP). The transmitters we produce (NRP, RNB or RTS) have a set output power 10 dBm - measured on the BNC socket. To meet the requirements, the antenna path must be in place insert a 10dB attenuator or, for example, use an additional section of coaxial cable, which will reduce the radiated power to an acceptable level. IN case of using the RG58 cable, which has an attenuation of 35dB/100m for frequency 435MHz, a minimum of 28m of cable should be used. It is assumed that the remaining 1.5 dB will be lost on additional connectors.
