This is the first attempt - received ANRB today at midday - setup using supplied antenna mounted on a biscuit tin (full of gravel) -tin stood on flat roof just outside window.ANRB is on Window sill about 10 feet from PC (used USB extenders)
height above surrounding ground no more than 8 feet. building is approx 400ft amsl on the N sside of Torquay - looking directly across Lyme Bay towards the east.Land rise behind (West)steeeply for another 100-150 feet hence the sharp cutoff of range in that direction.
So far it has logged over 500 flights.
Am very pleased with performance so far - now planning to jack the antenna up a few feet - that hopefully will help with the western sector a little.

Dave,
Jack it up!
Cheers
What a difference a couple of feet more height and a decent (MD1105 GP) antenna makes.....
