I have the ACK model E-04 121.5/406 ELT. I planned to run the telephone cable from the unit to the panel in the same cable run as my com antenna cable until I read at the top of pg 9 of the ELT install manual (http://www.ackavionics.com/pdf/E-04 Install Man Single Page.pdf)
It says to avoid running this cable with strong EMI/RFI radiation, i.e. com cables.
Has anyone out there run these 2 cables together and has there been any interference? The telephone cable to the panel goes to the audio alert indicator then to the remote control switches.
Edit.....I emailed ACK the above question and this is their reply:
"I don't think it would cause any problems early ELT were susceptible to being set off by high levels of RF/EMI. The newer ELT are quite resistant to this problem however when possible it is good practice to separate them."
So I am going to route cables together in a flexible cable wrap and test it out. It there is interference then I will have to pull one of the cables out and reroute.
