Product Description
Terrestrial Satellite Masthead Diplexer F-Type Screened - combines/splits all terrestrial bands (5-854MHz) SAT IF
Features:
- High-isolation frequency-selective units for combining or splitting signals in the various terrestrial and satellite IF bands.
- Very high isolation from SAT ports at UHF, avoids excessive signal degradation due to LNB noise.
- Fully screened RF modules in robust diecast enclosures. Strong cast-in 'F' connectors.
- Power pass (20V and 400mA max.) to the higher or highest frequency port.
- Two NEW products add Band III coverage for DAB or TV to this range for the first time.
- With equipotential bonding point.
- Suitable for indoor or out door use.
- PROCOM21TS Diplexer, combines or splits all terrestrial bands (5 - 854MHz) and SAT IF.
- PROCOM31T Triplexer, combines or splits three individual terrestrial bands.

I bought a 4-way distribution amplifier to replace an old one made by another company. Ordering and delivery went as planned. The amplifier is a solid piece of kit, built to last. Easy to fit. Works well. Nice one !
