A Log Periodic TV aerial has many benefits over traditional wideband TV aerials. For a start, Log Periodic aerials have a flat signal gain characteristic, meaning that they work equally well on all UHF TV channels - making them truly wideband and more likely to give consistent signal strength on all Freeview channels. By contrast, normal wideband TV aerials are very much a compromise and work much less well on the lower Group A UHF channels, making them less suitable for use in the London area for example - where all TV channels are in Group A.
Log Periodics are well built and resistant to element damage, making them ideal for caravan or boat installation where the antenna is frequently taken down and equally suitable for home installation in a loft or outdoors.
A Log Periodic TV aerial is perfect for digital reception as it rejects impulse noise much better than a traditional Yagi aerial. Impulse noise is the largest cause of picture freezing and signal dropout on Freeview reception. Logs also offer much improved rejection of unwanted signals from other transmitters eminating from the back or side of the aerial - due to the Log Periodic's tight polar diagram.
A good quality log periodic TV aerial like the Triax TL 40F, will work well on all UK TV channels and be suitable for use on all main and relay TV transmitters in the UK. It is light and easy to install in a loft space or outdoors and can be mounted with vertical or horizontal polarisation.
As there is no large reflector, the wind loading on a Log Periodic aerial is much less than with a traditional Yagi TV aerial, so the aerial can often be mounted on a longer pole leading to much better results than much larger more visually obtrusive aerials. This often amply makes up for the fact that the Triax TL 40F has slightly lower signal gain on the Group B and Group C/D UHF channels than a conventional Yagi-type wideband aerial.
