The RGS10-48 receiving antenna is designed to operate over the frequency range of 329 to 336 MHz. The RGS10-48 is horizontally polarized and designed to receive the glideslope portion of the ILS system. Constructed of epoxy materials and fiberglass, the RGS10-48 antenna is flexible, thus allowing mounting inside a nose radome, on a windshield, vertical structural member, or any flat or concave surface.
