Using a Yagi Antenna

At my indoor location a connection to the local cell tower is mostly non-existent and to enable bench testing I have recently set up two 11db gain Yagi Antenna.

The reason for two antenna is to enable simultaneous up and down links without insertion loss from the use of a splitter/combiner.

These antennae are the same as the one on my sales page and are working well, providing a steady 2 to 3 out of 5 bars on the Acorn wireless cameras. Since I installed them I've been able to carry out tests with a consistent almost 100% sending performance sending

This web site is about the wildlife, particularly the mammals, of the Glen Affric National Nature Reserve area in the north west Highlands of Scotland, UK; and the equipment I use to search for them, which is chiefly trail cameras.

I provide a technical support and parts service for the Ltl Acorn range of cameras and the income from this provides for the upkeep of this site and the purchase of cameras for my own surveying.

I hope you find the site useful and informative; and please contact me if you have any questions that I haven't already covered.
