The AT-1108-1 antenna is a combined VHF/UHF airborne communications antenna. The outside surfaces of the antenna are abrasive resistance fiberglass epoxy and the inside is filled with foam to reduce the effect of extreme temperature changes, extreme humidity, and excessive shock and vibration. The antenna is produced to meet the electrical requirements of MIL-E-5400, and the environmental requirements of MIL-STD-810. Drag force on the antenna at Seal Level and at sub zero (0) angle of attack is 1.0 lb at 250 mph and 2.5 lb at 400 mph. The isolation between the bands is > 40 dB. A gasket for RF shielding and positive sealing is included. The antenna is coated with a Skydrol resistant lusterless CARC black paint.
