- Barrett P/N’s BC91200, BC91202 and BC91203
Barrett 912 broadband dipoles are ideal for base stations that require operation on multiple
frequencies throughout the HF spectrum using a single antenna.
The Barrett 912 antenna can be mounted either in a horizontal or inverted 'V' configuration
as illustrated in the following diagrams. In the horizontal configuration the major radiation
direction is broadside to the antenna. When mounted in the inverted 'V' configuration the
antenna becomes fairly omnidirectional. In the horizontal configuration the minimum
distance between the masts is 32 metres and the recommended mast height is 15 metres.
In the inverted 'V' configuration the recommended mast height is 15 metres and at this
height the 2 metre stub masts are each installed at a minimum of 9 metres from the mast
base. In this configuration the mast must have an offset or out-rigger bracket, at least 0.8
metres long, to hold the antenna away from the mast. Support towers may be either lattice
masts as illustrated, tubular telomasts or other support structures that may be available
locally. It is recommended that the halyards used to support the antenna be either UV
stabilised dacron chord or wire rope and that pulleys should be of stainless steel
construction.
