2 Meter Amateur Radio J-Pole Antenna

$46.00$50.00

Our flagship model, The Two Meter J-Pole Antenna comes as a two piece breakaway model for easy storage and transport. The two piece antenna has the same specs and performance as the single piece model.

Please see my article on shipping and product changes for more information

The J-Pole makes a great base station and emcomm emergency communications amateur radio and scanner antenna. Works well with handheld HT radios, base stations, and repeaters. Ruggedly constructed one piece design, this J-Pole antenna will last practically forever. Copper has an extremely low electrical resistance, making it one of the most efficient materials for RF radiation.

The Breakaway 2 meter J-Pole is the same antenna as the original model but with a two piece design. Same dimensions and specs as the original J-Pole but with a screw connector in the middle for easy transport and storage. Now the antenna will fit in the trunk of your car. Carry it with you for fast emergency communications deployment.

Description

Benefits:

  • Rugged construction for years of reliable service
  • Low noise floor picks up weak signals better than comparable wire or plastic enclosed antennas
  • Wide bandwidth, (4+ MHz across the 2 meter band). No need to retune
  • Omnidirectional RF radiation pattern is balanced for communicating with stations at or slightly above the horizon line.
  • Pretuned and ready to go for the 2 meter amateur radio band

The only difference between the 2 meter J-Pole and the 2 meter Break-away model is the addition of the screw connector in the middle for easy storage and transport. I like to take this particular antenna camping as the two piece design takes up less space than the one piece antenna.

There are literally hundreds of antennas on the market, what makes this antenna any better than some of the higher priced you’ve seen or experienced? The simple answer is that it just plain works great. Dollar for dollar, the KB9VBR J-Pole antenna may be the best value on the amateur radio antenna market.

Dual Band Performance in a single antenna:

Each antenna is individually tested and tuned for optimum performance on their respective bands. The two meter antenna is tuned to 146MHZ (1.2:1 SWR or less at 146MHz), and the SWR is 1.4:1 or less throughout the entire 2 meter band. This antenna also works great as a dual band antenna. The antenna will tune up on 70cm for excellent dual band performance.
