I use this for internal. Before that I had such a "effe" little old antenna. This always disturbances or sent any photos. That bugged me enormous.
Thanks to this new and very strong antenna, I always receive full and clear, clear picture.
I believe in the whole 2 years, I had once put the antenna shortly different because the reception was disturbed. Anyway ... Why?
Well do not care.
For this money you definitely get a great antenna for me at least in 99.99% has ALWAYS full receive and transmit a clean signal. Simple Top.!
What better I have not yet found.
A strong buy recommendation !!!
