JG ULNA70VOX-E Mast preamplifier 430 MHz UHF - VOX 100W very low NF

JG ULNA70VOX-E

UHF preamplifier for the 430MHz band (70 centimetres) for pole mounting 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 working without any external accessories up to 100W. Perfect for sat, contest, trope and eme use. Can be connected directly between radio and antenna.

Field of use:

Preamplifier made of 4-layer PCB with integrated VOX circuit, coaxial relays and bias tee on board. It can work up to 100W and performs switching from TX to RX automatically.
INNOVATIVE Ultra Low Noise preamplifier. Low noise figure (typ. 0.35dB with active coaxial relay).
Thanks to the LTE notch filter present at the input it is possible to attenuate interference from LTE networks. Made in our cylindrical anticorodal aluminum structure.
It can be powered, in addition to the pass-through capacitor, also via BIAS TEE with a voltage from 9 to 15V and a maximum absorption current of 135 mA.

Uniqueness:

Coaxial relays on board up to 100W transit
INTEGRATED vox circuit
Powered via Bias tee with voltage from 9 to 15V
Low noise figure at 430 MHz (typ. 0.35dB)
Band pass filter
LTE input notch filter
