I have previously other (active) antennas tried with rather bad result.
To make it short: Only the Surfstick: 1-2 bar about 1 Mbits downstream. The antenna then full stop and 8Mbits downstream. So I was also satisfied.
The antenna is not suitable for outdoor use but a little splash they coped then already ...
I had now in operation since mid-February and has been exposed to wind and weather today.
(And the climate on the north side of Lake Lungern can ever be a little gruff ...)
I do not know whether that is durable good but for me it has worked up to now and tomorrow they will be dismantled anyway (moving ...)
It is important that you accurately align the antenna and sometimes 90 degrees rotated (polarization) or the connector swapped on Surfstick if it does not want to fold the same ...
Have fun with it!
