PREAMPLIFIERS

JG HITECHNOLOGY is pleased to present its line of coaxial and pole preamps for HF VHF and UHF frequencies.

All our preamplifiers use the latest generation components and offer very low insertion losses, sometimes less than 0.2dB.

We can supply preamplifiers calibrated to specific frequencies on request.
