Whoever installed this Televes aerial (the one with the yellow bling) obviously couldn't be bothered to install a new bracket and mast. Instead they have just clamped it to an old mast and scarpered. I personally don't like these Televes aerials. The larger ones (DAT45 / DAT75) just don't provide enough extra gain to warrant the massive extra weight / wind loading, and they all seem to have this yellow / orange plastic which becomes incredibly brittle after a few months and cracks if you so much as look at it. The old aerial on top has the wire going diagonally........
