Product Description
4-Way External Masthead Splitter/Combiner Screened with Power Pass; 1 Input; 4 Output
Screened wideband units intended for splitting digital aerial feeds in strong signal conditions where the use of distribution amplifiers or active splitters is unnecessary. These products can also be used as general-purpose signal splitters or combiners.
Features:
- 2- and 4-way models available.
- Low insertion loss with excellent 75Ω impedance matching and high isolation between outputs.
- Fully screened RF modules in robust diecast enclosures. Strong cast-in 'F' connectors.
- Proven free-draining moulded enclosures give easy access and cannot trap water.
- Directional power pass (20V and 250mA max.) from any output leg to the common input, allowing an upstream amplifier to be powered.
- With equipotential bonding point.
- Suitable for indoor or outdoor use.

First class website and easy to navigate when buying items from Blake UK. Was emailed every step for reassurance regarding my on-line order for a stress free purchase. Will definitely be doing another on-line order from Blake UK regarding a TV ariel along with a loft bracket as I will be buying a loft Ariel in a few months time for my home. 💯% satisfied with my order 👍

I’m pleased with the ærial overall. I did have to fix two separate issues though… 1. Many of the elements were bent, some quite badly. Happily they all bent straight again without any fatigue fracture. 2. Many of the elements were not seated properly in the booms. In one case, a vertical element was touching one on the other boom. I was able to pull the unseated ones out to seat better but I’m not sure how long they’ll stay like this.

Blake UK provide an outstanding service. We recently moved into a new home and the existing TV signal reception was limited to a few flaky channels. I have never faced an issue like this before and wasn't sure if our smart TV, cabling or aerial were at fault. Rhys and the comprehensive information on the Blake UK website (including directional data for my nearest transmitter) resolved the problem very fast. A new and specific aerial, mast pole, clamps and instructions were efficiently dispatched and received the following day. I now have 844 channels! I should mention that during the installation the option to check signal strength and clarity on a Sony Bravia TV can be found in the 'Settings / Help / Signal Diagnostics' menu section.

Ordered an aerial, 4 way distribution unit & loft fitting kit. Very impressed with the items. They look & feel good quality, everything you need is included even the fixing screws. Very easy to fit.

I was looking for some roof hardware and found what I needed at Blake at a competitive price. I'm glad I bought through them because the transaction was simple and the delivery lightning fast. Received what I ordered on time and happy with the quality. So definitely will use them again.
