Exceptional HF 5Band WARC Antenna 5B11HD

Excellent heavy-duty HF 5Band WARC Antenna 5B11HD covers 20m, 17m, 15m, 12m, and 10m bands with central wide-spaced elements that can fit in antenna towers up to 0.7m wide. Good for antenna stacks.

Intended for DX hunting on WARC bands and contesting.

Rugged construction. Strong boom (60 x 60 mm) and sturdy initial diameters of elements will ensure high resistance to high winds and snow.
20m starting element diameter 35 mm.
15m starting element diameter 30 mm
10m starting diameter of elements 25 mm.

What does 5B11HD mean?

5B – Covers 5 bands 20m, 17m, 15m, 12m and 10m
11 – Elements
HD – Heavy Duty construction.

HF 5Band antenna 5B11HD can fit in the middle of rotary towers or on the top. OK for towers not wider than 0.7 m. It will perfectly fit with about 16.5 cm of space from all elements to the tower. Ideal for a Five-band stack.

The antenna uses a common feed line. Input power is limited by the feed line only. Very low SWR on all five bands

Antennas-Amplifiers Product Benefits. A Major advance in Amateur Radio antenna design.

 

• Gain and F/B superiority.

All antennas have been calculated using state-of-the-art full 3D Electromagnetic Simulation Software including the influence of the boom, bracket, baluns, and connectors.
The performance of antennas designed using these techniques is exceptional, far better than antennas designed using “wire” programs.

Comparison of EM simulation software

• No tuning antennas
  

Before dispatch, we assemble each antenna and test antenna characteristics. That means you may expect exceptionally good electrical and mechanical characteristics including low SWR across the designed range immediately after assembling.
No need to tune the dipole, or any other element to get perfect SWR on the intended frequency range. Everything is pre-tuned.

• Easy to set up

Everything is labeled, just put number to number. The antenna can be assembled with hand tools.
Everything is included in the antenna box: Antenna, balun with connector, bracket, and pre-set guy rope support. Yours is to assemble and have fun!
