VSWR 1.35:1 typ..; 1.8:1 max.
Gain +11.5 dbic min.
Beamwidth @ -3 db 35° min.
Side lobes -13 db typical
Polarization  Right Hand Circular
Power Handling 500 W Peak; 100 W avg.
Size 7.00" Ø @ base; 1.73" Ø @ cylinder x 11.19" long
Weight 15 ounces max.

Shown: P/N: ADC5459 with Flange FLNG9227

Our models ADC5459 and ADC8895 are small helical antennas which are constructed of quartz and stainless steel materials.  These materials allow the antenna to operate in a 1000ºF environment for up to five minutes, with short heat pulses for up to 3000ºF.  The helix design achieves better than a 2.0 voltage axial ratio with a right hand circular polarization.  Left hand polarization and other frequencies are available.  

Flange part number FLNG9227 is sold separately. The flange allows the antenna to mount flush and to accommodate a skin thickness of up to 1/2 inch.
