Product Description
Dual Mode 4-Way Amplifier, Line Powered, With Return Path with PROPSU11F Power Supply
Features:- This versatile 4-way UHF amplifier can provide high-quality digital signals around the home and is particularly suitable for the multi-digital box household, whether using Freeview™,Sky™ or both.
- Has an equipotential bonding point.
Dual mode operation:
- Mode 1: AERIAL AMPLIFIER MODE (GREEN LED) In this mode the device acts as a normal 4 way UHF amplifier.
Apply power to the local power port, or power remotely via any output, and the unit behaves as a simple 4-way UHF amplifier. All return-path features are disabled in this mode. - Mode 2: RETURN PATH SKY MODE (ORANGE LED) In this mode return path is automatically enabled when the amplifier is powered via the input (EG from RF2). Feeding the input from the RF OUT-2 output of a Sky&trade receiver activates the return-path features allowing remote control of the satellite box using PROSAT1EYE infrared eyes.
Flexible powering:
- Power locally for Mode 1 using a PROPSA125 (where mains available). Alternatively power remotely via any output using a PROPSU11F, PROPSU12F, suitable Freeview™ box or IDTV.
- In Mode 2 the complete 4-way system can be powered entirely from either an old style Sky™ box or a PROPSU11F via aPROLINK22 (Flexible RF Output Modulator - restores Sky™ distribution) for one of new design Sky™ Boxes that have that they have no RF2 connection. See link below for more details.

Introducing the PROception PROLINK22 RF replicator:
New Sky™ set-top boxes such as the DRX595 and DRX890W do not have the familiar aerial input, RF-1 and RF-2 connectors. These RF-loop through facilities have been replaced with the new I/O PORT a small round connector (10- pin mini-DIN) which allows an external RF replicator (modulator) unit to provide similar distribution functions.

Fast and easy service with good quality goods

Good intial service, products arrived safely. Downside, found the products about 50% cheaper at another retailer who are reliable and trusted, so not lower quality and the aerial which was recommended for my area is not suitable and the quality of reception is worse then the original aerial.

I needed a custom size aerial tube bent. Blake were quick off the mark to give a quote (very reasonable) and after paying, I had the finished item a few days later by courier. Excellent service, and the finished tube was accurately bent to the drawing.
