I mounted mine fwd of the firewall, as far up as possible. I have been told the thing will work fine there by many users, but my luck does not always work the way I want it to.
I?m gonna also put a switch/breaker on the TXP circuit, and also run the GDL power on that circuit so any formation flying can be done ?clean?. Again, many others say this is a good setup for formation work.
I expect to get the system up and running this week. - I will report back either way.
