UHF 8-element Folded Dipole Antenna 400-470 mHz,12 dBd 300W

Description

ADxx0x series is a single or  several dipole array wide band VHF/UHF antennas for extensive range of applications – trunking radio systems, military communications, dispatch base stations, amateur radio repeaters, etc.
More gain is achieved by coupling single folded dipoles into arrays. The horizontal radiation pattern is adjusted by changing the distance between dipole elements and supporting mast.
Each dipole includes clamps for mounting to a customer supplied mast or a round tower leg which is 1.5” - 2.5” OD.
AD 4508 is a eight-dipole element array wide band UHF antenna for professional radio systems. Dipole incorporates “balun” matching circuit optimized for wide bandwidth and accurate matching. More gain is achieved by coupling single folded dipoles into arrays. Dipoles in array are coupled by precision phasing cable harness keeping low SWR and minimum insertion losses. All antenna parts are made of aluminium and covered with polymer powdered coating which resists water and ice buildup, and provides exceptional protection from corrosive gases, UV radiation, salt spray, acid rain and windblown abrasives. All components of dipole elements are DCgrounded for better lighting and antistatic protection. The boom is mounted to the mast (Ø 30- 55 mm) through the omega clamp with U-bolts.
The phasing cable harness is fully waterproof and protected against hostile environments. Feed cable terminates with N type female connector, nominal impedance–50 Ohm.

It is a serially manufacturing antennas, it is has a high quality and reliability.
Note: each antenna produced at a personal desired customer frequency, so when you place order, let me know your desired central frequency.
Usually, we ship out the antennas by Ukrpost, but if you want faster delivery, for extra pay, we can send it by UPS express.
