Aerial Lingus

At the top there’s a ‘billboard’ UHF aerial, with an Antiference LP7 log-periodic below it. Antiference must have made a few bob over the years selling these into Ireland, because the country seems to have one on almost every chimney.  The gain of these aerials is modest, but like all logs they have good directional characteristics, and so are regarded as ‘ghost killers’.

The lower aerial is a wideband type based on the yagi design but with two dipoles. This arrangement is intended to reduce pick-up from the rear, and can also increase bandwidth. This example originally had two reflectors mounted on a rear cross arm.
