This post is number 2100 in a continuing series of simple ham radio antennas. In this well-made video, "Tinker John" (W5CYF) guides us through the design, construction, and building of a simple 9:1 UnUn for use with long wire antennas. The device is cheap and easy to build--something John calls a "nice one-evening project." The finished project is suitable for both home and portable operations.

This is post 2098 in a continuing series of simple ham radio antennas. Radio amateurs involved in SATCOM or UHF experiments, may be interested in this portable SATCOM antenna from GATR Technologies. The antenna can be air-dropped and set up easily by communications specialists on the ground.  While this antenna and its delivery system have a direct military application, they can be used by a variety of public service, commercial, and amateur/ham radio personnel. In this video, GATR Technologies explains how the integrated system works: "GATR is revolutionizing the ultra-portable SATCOM industry with its inflatable communications terminal. Compared to other deployable rigid dishes of comparable size, GATR’s unique shape and designs enable extreme portability, lower cost of ownership, reliability in extreme environments, and ease of set

If you want to make a simple 40 meter dipole antenna capable of covering several HF bands, you will need a balanced feed line and a balanced antenna "tuner". In this well-organized video, Australian radio amateur Peter Parker (VK3YE) shows us how to make a simple balanced antenna "coupler" in conjunction with a balanced feed line to extend the frequency coverage of a basic 40 meter dipole antenna. Here are some of Peter's suggestions for this project: "Not your ordinary 7 MHz dipole. This works on all bands up to 28 MHz. It achieves this with a home made tuned feedline and balanced antenna coupler which is described in the video. The antenna is 20 metres from end to end while the feedline is about 8m long (neither critical). I only had
