16ft alloy mast In certain circumstances (e.g. bungalows) a 10ft mast is not enough so a 16ft mast must be used. This also requires extra bracketry to keep it secure to your property. High-gain benchmarked aerial In extreme circumstances our standard low-gain and medium-gain aerials are not able to provide a good enough signal. In these situations a high-gain or super high-gain aerial is required. Freeview TV aerial installation Includes benchmarked aerial, alloy mast (up to 10ft), galvanised bracket, single benchmarked co-axial cable run (up to 20m), connectors, cable clips and 5 year warranty. Freeview Installation Freeview, aerial, UHF, normal TV.... Whatever you call it!
