1. Size. The 2 meter J-Pole is less than 6 feet tall. The breakaway model folds down to under 36 inches. The antenna is small enough that it can fit in the trunk of your car without taking up too much space.
2. Performance. The J-Pole has about 2.5db of gain over a 1/4 wave antenna. It’s a half wave design, so it has a doughnut shaped radiation pattern; sending more RF energy to the horizon than the sky. Also, building the antenna out of 1/2 inch copper tubing both increases the bandwidth and reduces the noise floor of the antenna. You’ll get better reception capabilities and a wider range of operating frequencies.
3. Cost. Probably the biggest factor; the J-Pole is inexpensive. You can dedicate this antenna to Emcomm use without breaking the bank. A similar single band commercial antenna is $80 or more; the 2 meter J-Pole is under $30.00.

As an active ARES/RACES member, the J-Pole is part of my go kit. If I didn’t recommend it, I wouldn’t sell it.

KB9VBR 2 meter J-Pole antenna

This is the original KB9VBR all copper 2 meter J-Pole antenna. Ruggedly constructed one piece design, this antenna will last practically forever. The specs for the two meter version are as follows: Overall length 69 inches, radiator 58 inches, matching stub 19 inches. An S0-239 connector is soldered on at the point of lowest SWR.

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 loads up on 70cm for excellent dual band performance. Gain on this omnidirectional antenna is about 3db over a 1/4 wave groundplane. This style of antenna has been said to outperform a Ringo Ranger.

I got the 2 meter J-Pole about a week or two ago and just now finally got it mounted. Very nice! I have been reading the Missouri repeater directory trying to see how many repeaters I can hit. So far, the furthest is 90 miles away. I was actually taken by suprise when I keyed up, said my call and got a repeater beep back! I was not expecting to hit one that far away. Talked on another repeater that was 60 miles away and he stated I was full quieting. Very awesome! – Andrew WA0TFV

This is a super antenna for any situation. Great for base stations, this antenna can be mounted on a mast, tower or even strapped to an apartment balcony. This is at terrific antenna for digital communications; use it on your packet, dx cluster or APRS station. Also great for portable use, and the rugged design makes it an excellent emergency antenna. some people even use it as a VHF scanner antenna. If you have anyquestions, please go to my contact page.The perennial favorite here and on eBay. This antenna has outstanding performance on 2m and also loads up well on 70cm. Overall length is 69 inches with an 11 inch mounting stub. SO-239 connector is soldered on at the point of lowestSWR.

KB9VBR UHF J-Pole antenna

GMRS radios are gaining in popularity daily. Inexpensive and effective, these radios are redefining how families keep in touch. Unfortunately you won’t get the range you need unless you have a good antenna. The GMRS J-Pole is similar to the 440MHz antenna, but it is tuned for maximum performance on the 462MHz GMRS band. If your base radio can accept an external antenna (many of the better models can), then adding one of these antennas will greatly improve your range.

KB9VBR UHF J-Pole antenna

The 2 meter works great on the 70cm band, but sometimes you may want a 440MHz dedicated antenna. This is the one for you. Short, lightweight, and always more gain than a 1/4 wave groundplane; only 30 inches overall with an 11 inch mounting stub.

KB9vBR 6 meter J-Pole

This is my favorite antenna. A monster of an antenna measuring 13.5 feet; the six meter J-Pole will exceed your expectations. Click to see a full size picture. It outperforms most commercial antennas with its solid 3 db of gain. Excellent performance; hit repeaters 40 miles away with only 5 watts. The 6 meter J features a two piece design for shipping and easy storage. It is constructed of a combination of 3/4 and 1/2 inch copper tubing for rigidity and light weight. The antenna also has a stabilizer to keep the matching stub from swaying in the wind. The antenna is vertically polarzied for FM work and is pretuned to the 52.525 Mhz calling frequency.
