UHF CANTENNA CALCULATOR INSTALL
still really cheap".ĭo not install ANY antenna over, under or near power lines! If you need a "super" j, use a piece of 3/4" pvc as the insulator and add the stub and another 38 or so inches of conduit.
Make the "j"out of 1/4" soft copper, Solder it in place thru the hole and add the cable. A matching device should be used if you feed it with coax. Drill a 1/4" hole at the place where the "J" goes. The 5/8 wave antenna consists of a vertical radiator fed at the bottom of the antenna. Cantennator allows you to calculate the sizes of the popular home-made antennas for Wi-Fi, 3G-UMTS, 4G-LTE and other digital networks, including digital. "Iv'e built my j-poles out of 10ft sticks of 1/2" emt conduit. Use the last part of your feedline as the choke before attaching to the feedpoint! You should get good results with the choke within 3 or 4 inches of the feedpoint on 2 meters. For 2 meters, the coil is 4 turns of coax at 5 inches in diameter. We may also share this information with third parties for this purpose.On most of the J Pole designs out there, a choke should be used as close to the feedpoint of the antenna as possible to help prevent rf on the feedline and creating difficulty with SWR readings.
