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.

great communication - great experience

I was pleased with the price and items received however the experience was somewhat marred by DX Couriers. Expecting 2 items in the shipment they only delivered 1 and tracking confirmed 1 of 2 scanned onto delivery vehicle. When I contacted DX they confirmed the second parcel was still in Sheffield at the collection depot. This meant I had to wait in a second day for the rest of the order to arrive.
