Simple Ham Radio Antennas--Homebrew Slinky Ham Radio Antenna. Post #441.

Here's a nice weekend antenna idea from "Tinker John" (W5CYF). John gives us a step by step look at building a low cost (under $10) dipole antenna for 20 and 40 meters using the popular "Slinky" toy from Walmart. Add a few pieces of PVC pipe, some coax connectors, nuts and bolts, and a suitable length of 50 ohm coax and you're almost ready to go. Trim for the best SWR. I've built a few of these antennas and I've found 450 ohm ladder line into a balanced tuner (or into a 4:1 balun and then into an antenna tuner with short piece of RG-8X coax) works very well for this portable antenna. The slinky antenna works best on the higher HF bands (20 through 10 meters). Have fun! For the latest Amateur Radio news and events, please check out the blog sidebars.
