Triple Vestigal Side Band Modulator VHF Band 1 (B/G)

A common problem: A few additional TV channels have to be added; but the complete upper VHF & UHF spectrum is occupied.

Here comes a solution:

VHF Vestigal Sideband Modulator

The Triple VHF Band 1 Vestigal Side Band Modulator

In these days the VHF Band 1 (48,25 - 62,25MHz) is out of use in many regions.

This enables the use for distribution purposes with three additional TV channels.

TRIMOD offers a simple solution for this purpose. Three vestigal side band modulators are integrated in a compact module.

High frequency stability is achieved by the use of crystal oscillators. An integrated low-pass filter suppresses harmonics.
