The Terk HDTVa (also known as the Terk LOGTVA) combines a log-periodic UHF antenna, rabbit ears VHF antenna and a 12-decibel integrated signal amplifier into one very effective indoor antenna package. It's a great choice if you need a highly directional antenna, but you might need to reposition it regularly if channels in your area come in from different directions.
Great performance, but some downsides. The reception range of the Terk HDTVa -- up to 45 miles -- is excellent for an indoor antenna. This log-periodic UHF model is highly directional and less prone to multipath interference from reflected signals, which causes ghosts when watching analog TV but can completely obliterate digital signals. However, it also means you may need to constantly reposition the antenna for best results if you get channels from transmitters located in different directions from your home.
Hard to miss in a room. Many say the swept-back design of the antenna is relatively good-looking, but that's in the eye of the beholder, and the Terk HDTVa can't be as effectively hidden in a room as an antenna like the Mohu Leaf 30 (Est. $35). It's also a bit top-heavy and prone to tipping over, which can be even more of a nuisance if you need to constantly fiddle with the Terk HDTVa to bring in signals coming from different headings.
Could be overkill for some. Although it's less expensive than some antennas -- including some that don't perform as well -- the Terk HDTVa is a little pricey. If you don't absolutely require a directional antenna, and live relatively close to the transmitters, an omnidirectional antenna like the Mohu Leaf 30 (Est. $35), or even the Mohu Leaf Metro (Est. $20), can be an excellent alternative. But if you live in an area where multipath interference is an issue, the HDTVa may be your best choice.
Terk HDTVa Reviews
In this highly technical review, Putman conducts a three-antenna comparison test that includes the Terk HDTVa. He says the HDTVa "did the best overall job on UHF DTV and analog VHF signals, and the internal amplifier (although not a low-noise design) does make a difference."
