This antenna provides clients with quality, appearance and reception. It is almost 40cm long, and I've even on my underground garages - parking space knotless reception. Even in tunnels tears from the reception later, whereas I had absolutely no reception with the smaller antennas.
The thread convinced. There is a M5 - thread after I selected the antenna. It is resistant and rustproof. The base of the antenna is made of rubber, which lays down on the antenna socket on this when screwing. Thus, the thread and the base is reasonably weatherproof protected.
The antenna is flexible and visually it looks good.
That's why I forgive her 5 stars.
