Building Project: 9:1 UnUn & Long Wire Antenna

Image
  The secret to making a great long wire antenna is the building of a 9:1 UnUn to insure a proper match between the high impedance of the wire antenna and the low impedance of your HF transceiver. In this video, TinkerJohn (W5CYF), takes us through the design, building, and testing phase of this 9:1 Unun project.  The build is fairly simple, and you should be able to assemble the unit in just a few hours.

Here are a few comments from TinkerJohn (W5CYF): Simple and inexpensive to build the 9:1 end fed long wire antenna is a good antenna for both portable and home use. This antenna, like all antennas, has it advantages and disadvantage. You’ll see some of both in this how to video.

Amazing Cheap Multiband Delta-Loop Horizontal Antenna

Image
  Here's another great antenna idea from Callum (M0MCX). In this video, Callum designs, builds, tests, and uses an inexpensive horizontal delta loop antenna to cover the 40m, 20m, 15m, and 20m Amateur Radio Bands. Other than the cost of some wire and a 4:1 balun, the antenna can be built with items you may already have in your ham shack. I've built several delta-loops over the years, and wasn't disappointed in the result I received.  Callum's instructions are easy to understand.

Here are some thoughts from Callum (M0MCX): I am about to install a Multi-Band loop which will be resonant on 40m, 20m, 15m and 10m. It needs a 4:1 balun - but other than this balun, this is cheap to build and is well within the possibilities of many small ham radio stations. It will give me some TX and
