If you're searching for a light weight 2m antenna with good bandwidth and low SWR, please consider this antenna from VK6CS. Here are some general comments from VK6CS: A couple of things I should have mentioned. I live on a hill, so a good report from 30km away may have been far worse if I lived down at sea level. And, the antenna seems to have a pretty good bandwidth, the local repeater is on 146.700MHz, I went up and down in frequency by around 1 MHz and the SWR was very similar. The SWR is pretty low, I didn't measure it but it was just visible on the FT857 SWR meter. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Kitchen Foil Hula Hoop Loop for 15 to 10 meters

Thanks to Australian radio amateur Peter Parker (VK3YE) for this simple, ultra cheap magnetic loop antenna covering frequencies from 21 MHz through 30 MHz. The heart of this antenna arrangement is an old "Hula Hoop" and some ordinary aluminum foil.  Most of the antenna materials can be found in your neighborhood or at your home. If you've ever wanted to experiment with magnetic loop antennas at almost no expense, then this antenna from Peter is what you need.  The antenna works well, considering the type of materials used to make the project. ----- Thanks for joining us today.

How to camouflage a vertical antenna

If you ever wanted to conceal your ham radio antenna from nosey neighbors or the local HOA/CC&R group, then this camouflage idea from "Outdoors On The Air" could be of interest. Thanks to some paint and a number of trees, this vertical antenna is well hidden from peering eyes. Be sure the paint you select doesn't contain metal particles--they may hamper antenna performance. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

Callum McCormick's (M0MCX) "DX Commander Expedition Portable Ham Radio Antenna" is certainly a fascinating multiband vertical antenna.  In this video, Mike (K8MRD) and a few friends show us another way of building this impressive antenna, from unboxing the package to final performance tests. Here are a few comments and additional antenna links from Mike (K8MRD): A complete build of the DX Commander Expedition Ham Radio Antenna.

In part two of this experimental antenna project, Kevin Loughin (KB9RLW) completes his homemade indoor antenna and conducts a few on-air tests. Radio amateurs living indeed-restricted housing (HOAs/CC&Rs) should find the video interesting. Here are a few comments from Kevin: Had an idea. So here I am building a proof of concept rough prototype. Part two is here: https://www.youtube.com/watch?v=YDSQk...

Ham Radio-Prototyping an experimental antenna

Radio amateurs living in deed-restricted housing (HOAs/CC&Rs) will find this video from Kevin Loughin (KB9RLW) most interesting. Kevin does an excellent job of prototyping a few antenna designs for indoor or stealth use.  Kevin offers a few suggestions on how to build, test, and operate his experimental designs. All you need are a few inexpensive materials and the desire to build and test a few basic designs.  A compromise antenna is better than no antenna. Here are a few comments from Kevin: Had an idea. So here I am building a proof of concept rough prototype. Part two is here: https://www.youtube.com/watch?v=YDSQk...

Homebrew Slinky Ham Radio Antenna

Image
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Jo0QB83tdkQ&ab_channel=W5CYF%2FTinkerJohn Amateur Radio operators have used a variety of "experimental" antennas for their home and portable operations.  Among the more curious materials used for HF antennas is the "Slinky Dipole Antenna" based on the popular children's toy. In this video from "Tinker John" (W5CYF), we see how this expandable steel wire helix can be used as an emergency HF antenna. Because of the complex impedances involved, it may be best to use a balanced feeder (450-ohm window line) and a wide-range antenna "tuner" to keep SWR low and efficiency as high as possible. Here are some general comments from W5CYF: A step-by-step look at building a low cost (under $10) dipole antenna. The question is...will it work?
