JG ULNA70VOX-E
UHF Masthead Preamplifier for the 430MHz band (70 centimeters) with integrated VOX circuit, bias tee, and very low NF coaxial relays
UHF preamplifier for the 430 MHz band with integrated VOX circuit, bias tee, and on-board coaxial relays capable of operating up to 100W without any external accessories. Perfect for satellite, contest, tropo, and EME use. Can be connected directly between the radio and the antenna.
Area of use:
Preamplifier built on a 4-layer PCB with integrated VOX circuit, coaxial relays, and on-board bias tee. It can handle up to 100W and performs automatic TX to RX switching.
INNOVATIVE Ultra Low Noise Preamplifier. Low noise figure (typ. 0.35dB with active coaxial relay).
Thanks to the LTE notch filter at the input, it is possible to attenuate interference from LTE networks. Built in our anti-corodal aluminum cylindrical housing.
Can be powered, in addition to the feed-through capacitor, also via BIAS TEE with a voltage from 9 to 15V and a maximum current consumption of 135 mA.
Unique features:
On-board coaxial relays for up to 100W of through-power
