UHF Broadband Arrays

With their triple-wall masts, Cushcraft's heavy duty broadband arrays are rugged enough to withstand winds up

to 100 mph (161 kph). They are also DC grounded for lightning protection.

Ideal for use in public safety, business, industrial, state and national parks, or wherever a rugged, conveniently

sized omnidirectional antenna is required. Elements can be arranged for elliptical or omnidirectional coverage.

4068P/4508P Mountain Topper 9.3/12.3 gain

Our highest gain arrays are extremely heavy dutyt, thanks to thoroughly-coated dipole connections and molded

harness splices which provide lifelong weatherproofing. Harnesses are precisely assembled for proper phase and

impedance relationships to assure you of the best possible gain. The elements can be arranged to create any desired

radiation pattern, from omnidirectional to elliptical.

Choose either the 406-420 MHz 4068P or the 450-470 MHz 4508P.

These antennas are ideal for dedicated or community repeater applications.

Short Mountain Topper 4064P/4504P

6.8/9.8 dB gain

Half-size versions of the Mountain Topper, these antennas are

designed for applications requiring less gain but demanding the same

rugged performance characteristics. The 4064P offers a 406-420 MHz

frequency range, while the 4504P range is 450-470 MHz.

Four Dipole Arrays

You may customize these extremely rugged 450-470 MHz antennas

to provide offset or omnidirectional coverage by simply orienting the

elements.
