More information about dual band antenna 2n70WB19R

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, connectors… 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.

19 elements on a 2-meter/70cm band are on the antenna boom of just 2.92 meters long. Since this Ham Radio 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.

Weight 4,9 kg

1 review for Dual Band 2m 70cm Rear Mount Antenna 2m70WB19R

  1. Bborden

    I have had this antenna a little over a year now. It has allowed me to reach a repeater 25 miles away with at 5 watt hand held radio. I have the antenna on a 30’ mast and in vertical orientation. This antenna always gets a loud and clear from those on the receiving end of this thing even when single side band conversations have been tested. It was very easy to assemble and extremely light weight for its size. It is made of very durable material and I absolutely love it! It is a bit pricey especially to ship to the U.S.A. But soooo worth it! Wish I could give it more stars. Thanks for the great antenna!
