With a radical advanced design, for vertical omni directional VHF antennas the SPECTRAL IsoPole, has obtained a strong reputation through the years, offering exceptional characteristics compared with any other type of antennas as. O degree radiation angle, so the major lobe is oriented on the horizon giving the maximum gain on the length. Decoupling sleeves offer greater efficiency than the common radials, producing a uniform omni directional pattern and a great mechanical strength. Broader frequency coverage than other collinear antenna. They can be tuned for commercial, military or amateur applications without re-tuning across the entire band with less than 2:1 of SWR with no compromise for the transceiver.
Constructed with the best quality materials available of high resistance corrosion aluminium alloys, stainless steel mounting hardware, and insulation resistant to UV mainly manufactured for satellite applications; the connector is inside the mast fully weather protected, offering a linear and constant performance. It has a high noise threshold, capable of discriminating weak signals of spurious or static noises, and it is also DC grounded. The installation of the SPECTRAL IsoPole is very simple, it requires only a metallic tube (not supplied with the antenna for a reason of length) of 32mm (1-1/4in) and 3 meter (10 feet) for VHF (135-160) models, model of higher frequencies accept shorter masts, and the UHF models are supplied with their own masts and it is only necessary to spend a few minutes assembling and tuning by a simple length adjusting according to the chart. 165 euros for 1 antenna.
