Earlier this month I attended the Chelsea Amateur Radio Club (CARC) for a build night. The project for the evening was to build a few Tape Measure Yagi Antennas. The eventual goal with these Yagi antennas is to do Radio direction finding (RDF) at some point this summer. Here are a few pictures from the build night.
Here we are cutting the pipe to build the frame of the Yagi antenna.
Larry (KD8MZM) with the frame of the antenna put together. We are not gluing the parts together to make it easy to disassemble for storage and transport.
Sanding off the paint of the tape measure makes soldering possible.
In the antenna closest in the foreground, half of the driven element has been attached. In the background, you can see a completed Yagi antenna that is being repaired.
Larry (KD8MZM) and Jim (KD8RFW) working on getting the driven elements onto the boom. Note that the clamps to hold the elements to the boom will have to be opened to their limits in order to be able to fit over everything.
Ed (WD8RAT) and Larry (KD8MZM) tying the reflective element to the boom.
Here we are tinning a short piece of stranded wire to connect the two driven elements.
Here we are connecting the two driven elements together with the wire we prepared earlier. Note, the electrical tape acting as a holding device to keep from burning fingers. This is so that we can later attach an SWR meter and adjust the two driven elements for a good SWR reading. We did not have the appropriate 50 Ohm coax cable to attach, but this is when the coax would be attached as well.
Final assembly almost complete, minus the coax cable. Note the electrical tape on the end of the element by the copper wire. Putting it on the ends of all elements will complete the build.
Jim (KD8RFW), Ed (Wd8RAT), Josh (KD8UTQ), and Larry (KD8MZM) having a discussion on various aspects of a built Yagi Antenna and what each part is used for.
Thank you to the Chelsea Amateur Radio Club (CARC) for hosting the event and to Larry(KD8MZM) for leading the build. Thank you to Jim (KD8RFW) for putting down a tarp to prevent accidental damage to facilities. Thanks to Josh (KD8UTQ) who donated a few lengths of RG58U for antenna connections. And a great big Thank You to the Chelsea Police Department for providing space for CARC club meetings downtown. Monthly meetings are the 2nd Tuesday of each month at 7pm expect for July & August.
