Default Re: Triax UHF Aerial - info

Sometimes, if the first director is significantly shorter than the adjacent dipole, that can indicate a wideband aerial. If it is a wideband, then it would likely have poor gain at the lower UHF channels in Group A as used by Ridge Hill - a reputable installer would (should) have used a Group A antenna at the outset.
