When are JDA going fix up the Cave Hill transmitter/antenna?

For at least the past fortnight the reception we have been getting is very up and down. Some days we are able to get 16 channels while others only 9.

This seems to vary during the course of a day. I have re-tuned many times sometimes 9 and then 16 channels all in the course of a few minutes.

Weak or nil signals are getting more common particularly with Prime.

When everything is good it is great but of late very poor.

Is it the transmitter/antenna system or other issues?
