Have cursed more than once during the installation. Firstly, because the holder is so badly handled that even at the slightest touch it loses its paint - which use excessive rusting leads after 1 years, but also because of the extremely sensitive adjustment needs. After 1 years Service is the state, primarily the support - but also the antenna itself, more than questionable. With any luck, I will give her (the holder) for 1-2 years, then it turns to dust. The antenna has even get by normal weather conditions, a small crack on Housing. The two stars are there that it works in principle and is nicely inconspicuous.
