Not sure they’re weaker, TX’s are running at roughly the same power output as before, (give or take 50W?
Could be weaker in extreme fringe areas though, the extra loss might reduce the power by about half a dB, which would only be noticeable in fringe areas.
Rhema hasn’t moved yet, their electrician couldn’t make it on Friday, to run a new power circuit for their transmitter. I could’ve done it, but they didn’t contract me.
The new combiner port has been installed ready for them to plug into, they will move to the SeaFM site, sometime over the next 2 weeks.
Funny you should mention a different radiation pattern with the new antenna. It should be identical, & I’m going to do more testing, but I’ve noticed some areas where CoastFM had co-channel interference at the North end of the Coast & around Lake Macquarie, now only have minimal or no interference as the CoastFM signal is stronger, but then there’s places that now have noticeable interference that didn’t have it before. I’ve also found one particular spot where the interference has been moved about 500m - 1km further North with the new antenna.
