Some of the resources I use.
I make and fabricate a lot of the things I use. I make most all of my antennas, at least my none mobile antennas. All my wire antennas and a couple yagi’s. I’ve not made a lot of yagi’s. I made a 2 meter to get into a repeater well and a 6 meter antenna. The rest have been some kind wire antenna. Dipoles and Inverted V’s. I enjoy the challenge and learning aspect of making. As well most of my creations are a little cheaper than commercially available units.
» Ham radio band plan via ARRL
» I use this site to calc my dipoles. I know the formula but I don’t always have a calculator on me.
» After my fan-dipole project is over my next is a Delta Loop for twenty.
» Where I buy most of the commercially built products is Gigaparts. At one time I lived in Huntsville, where they are located, so I feel I should help out the home town folks.
» Ham Radio Practice Tests, this is where I prep before a test. You can choose individual parts to focus on or take an entire test. The feedback it gives on your test is useful in instructing you on what to study.
» QRZ.com, the goto site for ham stuff. Callsign lookups, forums, and just generally a lot of ham stuff.
