Dual, Triple and Quad Feed Exposed Dipole Array

Dual, Triple and Quad Feed Exposed Dipole Array

Frequency Range: 138-174 MHz
Gain: 2.0-2.5dBd

Dual, Triple, and Quad Feed Exposed Dipole Array
The (2)871F-70, (3)871F-70, and (4)871F-70 are wide band multiple antennas designed for multicoupled systems. The antenna offers a choice of radiation
patterns that are determined by the dipole-to-mast spacing.

• These antennas have internal cabling and are not field adjustable.
• Each antenna is offered in a 1/4, 3/8, or 1/2 wave pattern spacing versions.
• Typical antenna to antenna isolation is 30dB, versions with 40 dB of isolation
are also available.
• Heavy duty versions are available. Please contact Comprod Inc. Technical
support technician for consultation.
