It was designed with 4nec2 NEC based antenna modeler and optimizer for 145/220/440MHz bands. As most of you that have been reading my email bulletins, attending the hamfests and listening to my ARRL forum talks know, a dues increase is coming. 9" 5/8ʎon 2 meters is 50" and impedance matching is provided by a low inductance coil The above combination provides a base-loaded vertical antenna that works on 6 meters. There are times when you may need more gain than the standard J-Pole antenna. We have a good technical 'net on a Monday night by the AHARS guys. In the top, an element was placed as a driver for the 50 MHz band, transforming the upper part of the antenna to a 1/2 wave radiator for 6 meters (3 Db of gain over isotropic). Antenna Construction The dimensions for the 20, 17, 15, 12 and 10 meter bands are shown in Table 1. After taking it down, I found a number of. Antenna Hombrew 2meter: J. This design was chosen because of the simplicity, ease of construction and operation. 160 Meter Prediction. Please visit my Amazon A store for some great Radio Products. As the late spring and summer months heat up, six meters comes alive. Please allow. Yaesu FT-60R dual band ht. , base loaded with a coil, or top loaded with top hat wires) typically have an impedance close to 10 Ohms, and at best 20 Ohms. The design uses a matching system like a j-pole antenna. I use a J Pole for air band (122 MHz). 67 foot ground plane Three Quarter wave Vertical: 14. "qso-king" 160-6 meters 1. After some calculations I came to a 4 element yagi. Building And Tuning 2 Meter 144 Mhz Copper J Pole Antenna. 6 Meter Beacon List. Wanted: Plans for 1.
