Arrl Dual Band 2 M 70 Cm Handheld Yagi Antenna In this video, you'll get step by step directions and instruction for how to build arrl's dual band 2 m 70 cm handheld yagi antenna more. It can be assembled and disassembled in minutes and has excellent gain for its size. no tools necessary. it comes complete in a black carrying bag with step by step instructions. please note, the diplexer can only handle 10w input.
Arrl Dual Band 2 M 70 Cm Handheld Yagi Antenna In this video, wayne green (kb4dsf) takes us step by step through the set up and use of this handheld yagi antenna, specifically designed for amateur radio satellite communications. We have examined a design for a dual band directional antenna for 2 meters and 70 cm. the antenna falls into the category of utility beams, since it has modest forward gain, good front to back ratio, and a very wide operating bandwidth in all performance categories. Version 1: ultralight with 3,2 mm elements. version 2: with 8 and 10 mm elements (see down), built by sq9vpa. the 4 el. ultralight yagi for 2m can be used on 70cm with an swr of 1,5 without any changes. the pattern and the currents of the yagi are shown down. This repo contains simulations, pictures and 3d models to built your own dual band 2m (vhf) and 70cm (uhf) yagi. the simulation assumes 4 elements on 2 m and 7 elements on 70 cm.

Today we are going to build a yagi antenna designed for 2 meter and 70 cm ham radio bands. it can be used to communicate with amature radio satellites or to assist in getting into that repeater that is just a little to far away. It turns out that, for very little cost, you can make an antenna that can help you effectively use a satellite to communicate with another ham on a different part of the planet. New antenna for k5nd. this one is a 144 432 combo antenna that will be used for single op portable in the upcoming arrl september vhf contest. The operational frequencies for this antenna are within the vhf uhf amateur radio bands; 2 meter band including frequencies from 144 mhz to 148 mhz, and the 70 centimeter band including frequencies from 430 to 440mhz. the tuned circuit l3 c3. at the homebrew centre we have everything you will need .
