KB9VBR J-Pole Antennas

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.

Its difficult to find a good base antenna for the 222MHz band. Many of the manufacturers have given up on this banc, which is a shame. This baby will get you on the air with great signal reports. Getting on 220 is like having your own private repeater or simplex frequencies. Overall length of 49 inches with an 11 inch mounting stub.

Low Power FM radio is taking off like crazy. If you are putting together a community radio station, special interest broadcast station or just want to transmit Christmas music to go with your holiday lights display, then this antenna is for you. This is a great basic antenna for your low power FM transmitter. The LPFM J-Pole is vertically polarized with about 3db of gain. The average height is about 95 inches but varies slightly with the frequency it is tuned to. The antenna comes in two pieces with a screw connector in the middle for easy transport and storage. When you order this antenna, please tell me which frequency you want it tuned to, as each antenna is custom tuned when built.

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.

KB9VBR Airband J-Pole antenna

The airband J-Pole antenna is tuned for the 118 – 128 MHz aircraft band. Aviation fans prefer this antenna as it works well picking up both land based and airborne transmitters. Many Live-ATC sites are using this antenna to stream aviation transmissions to the Internet. This antenna will give you about 2.5 db of gain more than what you would get with a discone antenna. The antenna has a two piece design with a screw connector in the middle for easy transport and storage. Overall length of the antenna is about 80 inches with the 11 inch mounting section on the bottom. I normally tune this antenna to about 125MHz, which gives it enough bandwidth to cover the entire aircraft band. But if you wish to have the antenna centered on a specific frequency, please let me know when you order it and I’ll build one to suit.

The (airband) J-pole works fantastically great.  I’m receiving crystal clear transmissions that I couldn’t before.  I’m 10 miles from the airport on a hill, but the airport is on a hill as well with the Seattle skyscrapers between us.  Reception is stellar. - Garrett
