A two stack circularly polarized folded dipole antenna intended for the use in point to point or point to multi-point communication applications.
Standard polarization is right hand circular, left hand polarization may be supplied to order. | | | |
The design utilizes soldered or welded joints in the RF current path thereby minimizing intermodulation products from being produced by dissimilar metal junctions.
Dipole assemblies, mounting clamps and all hardware are manufactured from stainless steel with the reflector panel being constructed from aluminium.
Supplied complete with mounting clamps for attachment to a ø55-100mm vertical member. | | | |
Additional stacking configurations may be supplied to order.
Each antenna is individually tuned, tested and shipped ready to install. | | |
