Transmitting Antennas
General. The TPO Horizontal Panel Antennas series is designed for TV transmissions in UHF Band. Each antenna is composed of eight ice protected radiating elements, a stainlesssteel reflector, a fibreglass radome and mounting brackets.
DVT ready. The TPO - series antennas ensures total DTV compatibility and quality
Antenna systems. Stacking more antennas it's possible to obtain customized patterns, increase the gain and the power handling capacity according to user requirements. Customized pattern, electrical beam tilt and null fill are available upon request.
Broadband. Suitable for channel or broadband (470 - 860 MHz) operations with multi-channel combiners.
Water, icing, moisture protection. The input connector is protected against rain and icing by a special housing. The internal balun is also protected against water, icing and moisture ingress by a sealed housing.
State of the art mechanical design, employing the finest materials (stainless steel, non-corrosive brass, copper, virgin PTFE and fiberglass) resulting in long life service.
Lightning resistance is guaranteed by the DC ground potential of the entire antenna.
