ERI ALP Series II antennas deliver the versatility, power, and reliability that are the keys to success in today’s competitive broadcast marketplace. For full-power stations transitioning to new RF channels, ALP antennas offer field-proven solutions for interim antennas. Broadcasters with medium power requirements can benefit from this antenna’s lightweight, low wind load, and easy installation which provide reductions in installation time and costs.

For Low Power Television (LPTV) stations the new, higher power handling capabilities of the ALP UHF antennas make them the ideal choice for the higher ERP’s allowed for LPTV stations and TV translator facilities. ALP antennas offer the quality and performance needed to improve coverage and maintain competitiveness in today’s broadcast marketplace.

ALP Series II antennas are available with a large number of standard azimuth patterns and in models from 4-bays to 32 bays.

Mounting Information

All cable and power divider connections are gas pass connections and are intended to be placed under pressure to prevent the accumulation of moisture inside the cables and power divider. The antenna modules have gas block connections to maintain pressure in the cables. The antenna modules are not pressurized.

All ALP Series UHF television antennas are shipped with 15-inch (381 mm) standoff brackets for mounting on poles or tower legs from 1.5-inches (35 mm) to 7.5-inches (191 mm) OD. Standoff support pipes, face mount brackets, and mounts for larger diameter poles are available from ERI as optional items. Please contact ERI for a proposal for these requirements.
