Product Description
Masthead Triplexer UHF/DAB/FM F-Type Screened
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.

Very prompt reply re order unfortunately delivery by DPD failed to deliver to address even though there was a person in. DPD delivered to a local drop off point for collection, the so called local post office which not that local!!! Otherwise there would be 5 stars!!! Product great and fitted to cover entry point of Sky cables into building as SKy's product has failed , plastic cracked and fallen off.
