HF Portable-Choosing the right antenna

Image
Choosing the right antenna is a key factor in enjoying portable or field operations. In this video, Peter (G3OJV) of the "Waters and Stanton" video channel describes several simple antennas that can produce excellent results during SOTA (Summits On The Air) and POTA (Parks On The Air) operations. In this regard, you may find an End Fed Half Wave Antenna or the Chameleon MPAS 2.0 Modular Portable Antenna a good choice for your field activities.

Portable Masts For Amateur Radio

Image
An informative, easily understood discussion of portable antenna masts for field or portable Amateur Radio activities. Mark Grows (KG6LI) analyzes five popular mast assemblies and offers suggestions on how to match these masts to your requirements.

This is post 2395 in a continuing series of simple ham radio antennas. Here are some comment from Mark (KG6LI): This video looks at five different portable masts used for amateur radio activities. The intent is to give the viewer information so they can better evaluate their needs before purchasing a mast. We look at the following masts: Spiderbeams 12 Meter SOTAbeams 7000 HDS Jackite 31 Foot Poles and Holders PNH-22 Deluxe SOTAbeams Tactical Mini While these masts are evaluated we look into the needs for specific outdoor activities and how it affects the choice you make.

Ham Radio-End Fed Half Wave Three Band Antenna

Image
  If you live on a small urban lot, you may find this end fed half wave antenna idea from Tim (G5TM) worth your time.  Tim uses the popular "HyEndFed Antenna" to cover 10-20-40 meters without having to use an extensive ground radial system.

Here are some comments from Tim (G5TM): Possibly the easiest way to get 40 metres in a small garden. No ground radials or horizontal wires needed. And NO tuner.

I made a short 80m dipole-linear loading

Image
Another way to "squeeze" an 80 meter dipole on a small urban lot is to use linear loading to reduce the overall length of a half wave dipole antenna. In this video, Callum (M0MCX) explains the theoretical and practical applications of linear loaded dipole antennas and shows us how to design and build such antennas.

Here are some comments from Callum (M0MCX): Dipole legs are normally just under 25% for each dipole leg (depends on height above ground) but you can shorten this to between 16-18% by loading it up in a linear fashion. Tom (M0RMY) and I made one. Let's show you how we got on. Callum, M0MCX. DX Commander #dipole #80m #linearloading ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Ham Radio: Finished 80m Band Wire Spiral Loop

Image
After a month-and-a-half of effort, Mike (M0MSN) has finished his 80 meter Spiral Loop Antenna.  The final product works well and promises to produce excellent results on the often noisy 80 meter Amateur Radio Band.

Here are some comment from Mike (M0MSN): Well this has been a stop and start project, due to work commitments it has taken me over 6 weeks to complete this antenna, but the time spent, was worth it. I have to take my hat off to Frank and thank his for a great website (linked below) without his research and brilliant record keeping this project would not have got off the ground. Please check it out at : https://www.nonstopsystems.com/radio/... Now for a list of what is needed and measurements please refurbs to Franks website, I have followed the plans and instructions

20M vertical dipole-T2LT design

Image
Here's another great 20 meter antenna idea for radio amateurs facing restricted spaces on small urban lots. "Tech Minds" does a good job of explaining how the T2LT design works and listing some of the considerations needed to build this type of antenna.  The antenna is based on work done by Stuart (M0OVG).
