For the past few years, we have been serving our customers in the television, radio, production, post-production, and audio recording business for their diverse needs and requirements. Through this experience we come to realize that transmitter and studio equipment performance can only be good with equally good propagation system. Thus, we focus a little more on our transmitter and antenna products.

BATWING - Low and high band VHF antennas

The new ERI Batwing antenna, a horizontally polarized transmitting antenna, is available in single or multiple bay configurations (Maximum 6 bays for Ch. 2-3, 8 bays for Ch. 4-6 and 12 bays for Ch. 7-13.). The antennas are constructed of rugged galvanized steel and brass components mounted on a support pole, which can either be flange or bury mounted on top of the tower.

The ERI Batwing can be designed as an omnidirectional or a directional (peanut) pattern. Because of its wide band characteristics, the antenna can transmit multiple channels (NTSC/DTV) simultaneously.
