PA70-4-1.5B

PA70-4-1.5B 70MHz -  SKU: 0410 

Low Noise High Gain PA70-4-1.5 provides stunning performance across the 4 meter band: 70 – 70.5 MHz.

Antenna has been calculated with the latest full 3D Electromagnetic Simulation Software, with included the influence of the boom, brackets and connectors.

Performances of such way designed antenna are extraordinary better than antennas “designed” with just wire programs that can’t calculate influence of any metallic structure near the antenna elements.

Calculating with full 3D EM Software gives opportunity for uncompromised performance. Much better than any other world competition. High gain, heavy suppression of all side lobes.

Solid construction that can withstand strong gusts of wind of more than 160 km/h! All screw, nuts and bolts are stainless steel.

PA70-4-1.5B is pre tuned antenna.
Before dispatch, we assemble each and every antenna and test antenna characteristics. That means you can expect all the electrical and mechanical characteristics including low SWR across the designed range immediately after assembling.
No need to move, cut, tune or use rasp for any element to get perfect SWR on intended frequency range. Everything is pre tuned.

When assemble and test each antenna is complete with all washers, nuts, bolts guy rope supports etc. When packing all parts are already on antenna. Without possibilities to “forget” important parts to put in the box. So you will always receive complete antenna what we tested just before dispatching
