While I've never put a Talking House or IAM transmitter in a weather proof box, I've put a Talking Sign (the precursor to the ProCaster) and an AMT3000 in such enclosures, and supplied power and audio via inexpensive CAT5 (network) cable. I've had runs up to 100 feet with no issues (hum or otherwise).
The suggestion to use CAT-5 cabling to connect the Talking House+antenna to the DC power and audio sources was spot on. I think this pretty much cracks what iAMRadio has done in creating their outdoor transmitter. I just today tested my "Talking House in a Box" (see attached photo)
and it seems to be working fine.
Should it be deemed useful, I could write this up.

Any idea about range?
Not yet. My initial testing concerns were that some sort of reasonable signal could be picked up and that the CAT-5 cable was indeed a good choice for the remote connection. Once I get everything buttoned up, I'll have another go here in the neighborhood.
My subjective judgement is that the signal inside and around the house was comparable to my tests of the previous setup, which consisted of the wire antenna attached to a length of PVC erected atop the Vanagon and the TH inside.
During the event two years ago, reception was reported almost a half mile away from the transmitter. In mid-July I'll visit the event site, set it up, and do some quantitative range testing in and around the buildings.
Wondering: now that I have a 100+inch steel rod pointing at the sky, should I be concerned with lightning issues and, if so, what sort of remediation is doable? I'm less concerned about the TH (I have spares) than with safety in general.
I have a Rangemaster in operation where we incur and average of 90 Lightning storm days a year. No lightning damage. This is the highest average in the United States. I would not worry to much.
