SHP & LP Series FM Antennas

The SHP and the LP series antennas' original and distinctive design combines the exceptional engineering features of an internally fed, fully pressurized system with superior fabrication characterized by totally welded feed connections, rugged brass material and TIG welding.

When you combine an ERI antenna with an ERI Lambda mounting structure, pattern measurements and installation, you assure yourself of the best antenna/tower interaction. Our pattern measurement service help determine the effect of the mounting structure on the antenna's pattern, while our patterm optimization service helps improve the pattern's circularity through the addition of parasitically excited elements.
