Hi
I have the SSEJIM attenna. Attached to side of the hose on barge boards sticking over the roof. I have a with a 15m run of low loss coax. (The Westflex cable was going to be used. But was given cable from friend that was surplus to a microwave system he put in).
I get about 75 miles to the N,S,W. East approx 110miles according to my polar map. With a few spikes. I'm 10miles SW of LHR and one of the spikes goes out to the Atlantic just South of Ireland.
