You can improve reception by using a properly installed VHF antenna. Look for a VHF antenna that is “V” or “T” configured, commonly referred to as Yagi antenna. The antenna you purchase should be rated for the distance from your furthest transmission.
UHF antennas, usually circular in shape, are not suitable for VHF high band reception, despite manufacturers’ claims. Some VHF antennas are also not suitable for VHF high band reception. Rabbit ears or indoor antenna are poor receptors for today’s demanding digital transmission.
For best reception, your antenna should be externally mounted. Because all VHF transmissions are line-of-sight, your antenna should be elevated above any nearby structures. Try to avoid mounting your antenna near trees. Water adversely affects DTV reception, and trees are buckets of water. It is common for spring to bring on poor DTV reception, due to tree leaf growth.
