On top, we have a 91 Element UHF Aerial, made by Hills Aerials
Below that we have a 6 Element VHF Low and High Band Aerial, made by Lincrad Aerials, below that on the mast is a 34dB Mast-head Amplifier + Diplexer, amplifies UHF only, VHF is only Diplexed, 0.5 dB loss and at 85dB(i) signal level at the TV, this is not a problem
On the roof we have a 600mm dia Sky Digital Dish, pointed towards Optus B2 at a Field Strength of 75 dB(m) we have a good picture.
UHF is a different story though, it hates mountains, as we have here and it is Line of Sight at the best of times, hence the Mast-head amp, the best I have seen is 35dB(i), at the Aerial.
Trees here block the signal out.
Anyone else have ideas on UHF signals?. [Linked Image]
