An OFC Dipole antenna was recently paid-forward to me. My Elmer friend let me borrow an antenna analyzer to check it out. I soon learned that the analyzer was actually put together from a kit. It is a very nice package with a sturdy case, touch screen interface, and an easy to understand user interface. Go to this page and see the AQRP 8KHz to 440MHz Vector Impedance Analyzer kit #25 for more details. It's well documented and a very slick package.

Right away I wanted to play with the analyzer and decided to sweep a few 2m hand held radio antennas as a test (results below).

- Kenwood TH-D72A Stock duckie antenna
- Nogoya NA-771 VHF/UHF aftermarket antenna duckie
- DIY 2m Tape Measure Yagi (instructions)

And, just for grins we swept a DIY simple wire dipole that was cut for 20m which is only use for Rx with a SDRPlay RSP1A. Our placement for the dipole is marginal and it works equally marginal on 20m and 40m. FWIW, here are the results:
