I'll only be using sat inputs. However, as we are on the edge of the satellite footprint I want to ensure that the multiswitch causes as few issues as possible in terms of losses from the input LNB. Which one would be best in terms of this - I don't really understand the input loss/gains and return losses? I'm more concerned in performance between these two items than price. Do the dials on the sat inputs make them easier or more difficult to set up?
You can stare yourself blind in specifications.
It's not really about signal strength - it's all about signal quality.
The main thing is the ease-of-integration, and this is where i found the EMP to excel - built-in amlificattion, support for quad LNBs etc.
(The Goobay claims the latter too, but I haven't tried it).
Forgive me if I misunderstand your setting, but your location does not strike me as being on the edge of any footprint.
I am 500 kms out of official footprint for Astra 2, and I still can use either device.
So, considering we are still talking a sub-100 GBP device, I think you will be well off with either.
If you want peace-of-mind, go with the EMP. If you feel like securing a bargain, go first for the Wenntronics.
