Open 2 meter 440 j pole antenna Optimized for 2 meters and covers 440 too BUILT PER DIRECTIONS IT COVERS ENTIRE 2M BAND. Ive built my j-poles out of 10ft sticks of 12. THIS ANTENNA IS BUILT ALMOST ENTIRELY OF HARDWARE STORE ITEMS WITH THE EXCEPTION OF THE FEEDPOINT CONNECTOR AND WORKS AS WELL OR BETTER THAN MOST COMMERCIAL ANTENNAS.

2 MetersAn All-Copper J-P01e By Michael P.
This article describes the J-440 a very simple J-pole gain antenna. For 2 meters the coil is 4 turns of coax at 5 inches in diameter. Use the last part of your feedline as the choke before attaching to the feedpoint. Hood KD8JB 2323 Jefferson Drive SE Grand Rapids Ml 49507-3148 number of years ago I built a J-Pole antenna from some scrap aluminum tubing and a 5-foot stick of TV mast. The Connect at measurement is 2 14 inches from the top of the horizontal member to the point of connection. Proper SWR and impedance on the 2 meter frequency first.
On Ham Radio Aj4rf We fabricated two identical J-Poles using the dimensions in this document and both of them performed quite well with a resonant frequency toward the lower end of the 2-meter.
| Topic: You should get good results with the choke within 3 or 4 inches of the feedpoint on 2 meters. On Ham Radio Aj4rf 2 Meter 440 J Pole Antenna |
