Ed Fong Antennas J-Pole Antenna for 144/440 Dual Band by Ed Fong This is the famous DBJ-1 dual band J-Pole antenna, designed and sold by Ed Fong - WB6IQN. This is a GREAT little antenna for performance. <a href="http://www.eham.net/reviews/detail/6377">See the eham reviews at this link.</a> Ed sells these antennas on ebay for $37. We are proud to offer them a somewhat lower price. Ed and I worked out a deal where we could buy his antennas in bulk and offer them for the same retail price that he sells them for. Email or call us with any questions. This antenna comes with everything needed, except the PVC pipe, which is exactly the same way that Ed sells them online. Go to Lowes and pickup some PVC item# 23990 which is PSI 200 pipe. DO NOT USE Schedule 40, only use PSI200, which is thinner and was used in the original design of this antenna. We'll also carry some of this PVC in the store for an extra charge - pre-cut to specifically fit this and other antennas. 5 stars, based on 1 reviews 0 5

Note from Ed about this antenna:

Dual Band VHF/UHF (144-148MHz and 440-450MHz) Base Antenna

Thanks for purchasing the DBJ-1 ham version antenna. If you are intersted in understanding how this antenna works and why it works so well, a complete explanation is given in the February 2003 QST. You can email me for a copy of the article. It is, as far as we know, a novel design. I am also more than happy to give a seminar to your ham group if you are looking for guest speakers via Skype or is you are within driving distance. Email me for details at: edsantennas@gmail.com

Basic Specifications:

Overall Length: 5 feet, 50 ohm feed impredance, no ground radials. Antenna feedpoint is 10 inches above the connector. Thus U-clamps, hose clamps, etc. can be used for mounting up to the first 10 inches of the antenna without affecting performance. The antenna offers “true” 1/2 wavelength radiator at both VHF and UHF.

VHF 144-148MHz
Configuration: 1/2 wave radiating element
Max power: 75 watts
SWR: less than 1.5:1 over 3MHz bandwidth and less than 1.7:1 over 4MHz bandwidth
Gain: 2.1 dBi
Impedance: 50 ohms

UHF 440-450MHz
Configuration: 1/2 wave radiating element
Max power: 75 watts
SWR: less than 1.3:1 over 6MHz bandwidth
Gain: 2.1 dBi (6db gain over 2 meter J Pole used at 450MHz)
Impedance: 50 ohms
