More information about dual band antenna 2m70Wide18

The antenna is pre-tuned, so no need to move, cut, or use a rasp file for any element to get perfect SWR on the intended frequency range. As all our antennas are, this Ham Radio antenna has been designed with professional full-3D EM modeling software. The antenna is calculated with the influence of boom, balun, connector… Once the antenna is up in the air, you should expect solid SWR across the whole designed range, true gain, and F/B as given in the table.

The antenna is very easy to set up. Everything is labeled, just put number to number. The antenna can be assembled with hand tools, as well as with power tools.

Everything is included in the antenna box: Antenna, balun with connector, and bracket. Yours is to assemble and have fun!

 

All our 2 meter / 70 cm antennas are divided into 2 categories. Common Connector dual band antenna and Two Connector dual band antenna.
