Ultralight Tape Measure Yagi
So after recently building the DF Tape measure 2 meter yagi designed by WB2HOL as seen by following the link below, I decided to come up with a design of my own that would be lighter and more compact.
I started working on a antenna that included what I felt would make a good design better for my usage, and that included a visit to one of my favorite antenna parts supply outlets... Home Depot.
Some of the parts that I picked up at HD were a fiberglass ditch marker rod for the boom, the water line tees to mount the 5/8ths wide tape measure elements to, removed from a inexpensive tape measure, also purchased at Home Depot.
The 1/2" white pvc tubing material used for the handle, as well as used to fasten the elements in place, and shrink tube for the handle, I had left over from other antenna projects.
The total cost of parts was 9.95.
After completing the antenna, and making the necessary adjustments, to make it resonant on the fox-hunt frequency of 146.565 Mhz, I then swept the entire 2 meter band with my antenna analyzer, and it proved to have good SWR across the band.
My latest ultralight handheld yagi is going to be a great addition to my antenna arsenal for not only fox hunting, but once I modify the boom to allow it to be broken down further, it will be sized for fitting a day-pack, for hiking in the backcountry, giving me the extra reach required when paired with my Yaesu VX-8R.
