If you need a simple, inexpensive Amateur/Ham Radio 2m/70cm antenna for portable or even home use, then this 2 meter vertical dipole antenna from Dave Tadlock (KG0ZZ) may be be what you need. With a few hours of your time and some parts costing between $20 and $40, you can have a high performance vertical dipole which can be fed by 50-ohm coaxial cable. Here is a comment from Dave: A simple ham radio 2 meter and 70 cm antenna for fixed or portable use. For details: http://www.amateurradio.bz/2m-70cm_ve... ----- Thanks for joining us today.

Non invasive mobile antenna mount for truck bed

Here are some of his comments: This is a non invasive friction mount for a truck bed. This antenna mount will work with any stud type antenna. Its been on my truck for just under a year and has shown absolutely no sign of fatigue. I have linex on my bed, so I didn't bother with paint protection as I didn't need it, However a piece of rubber between the bed rail and the clamp should protect the paint. I apologize for my hand getting in front of the camera, I don't have someone to hold the camera and manipulating the camera with one hand while giving demonstrations is fairly difficult, especially when climbing under a truck. :P ----- Thanks for joining us today.

Thanks to Tim Carter (W3ATB), we see just how easy it is to talk with your fellow hams using this ultra-simple antenna. This NVIS (near vertical incidence skyway) antenna is also a good HF emergency antenna, providing usable communications out to approximately 300 miles/486 kilometers.   Don't expect long-range DX contacts with a NVIS antenna.  But, for local, state, and regional HF communications, you can't beat this classic antenna design. ----- Thanks for joining us today.

If you need an ultra simple and cheap 2 meter antenna, then this "Slim Jim" project from Kevin Loughin (KB9RLW) is just for you.  All you need are some basic tools and a length of 450 ohm ladder line. The antenna is perfect for portable or emergency field use. Here are some general comments from Kevin: Details on the slim jim I just made to use outside on my RV. Super easy to make, performs well.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=0XLURp33MBo&ab_channel=AirborneSurfer If you do a lot of weather satellite monitoring, you'll find this tutorial on QFH antennas (Quadrifilar Helix Antenna) most interesting. You can modify the antenna to cover GPS and Amateur/Ham Radio bands as well. Her are some general comment from the author: If you want to build an antenna to receive signals from a weather satellite, you will need a special kind of circular polarized antenna known as a quadrifilar helix antenna. In this video, we'll go through the theory and practice behind how to build a QFH antenna. These antennas are especially-made for NOAA weather satellite reception and are tuned to 137MHz to receive polar orbiting satellite signals. This is part of Project TIROS for element14 presents. You can watch the full build at https://www.element14.com/community/d... 🏄‍♂️ If you enjoy watching the

6 Meter Squalo Antenna Build

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=U3ZGJWuzgRs&ab_channel=K2CJBRadio Thanks to Cris (K2CJB) for this intriguing 6 Meter Antenna. The "Squalo" resembles the old 2 Meter "Halo" Antennas that were popular with mobile hams several decades ago. This antenna is compact, portable, and highly "stealthy" for those living in deed-restricted homes and apartments. Cris does an excellent job of taking us step-by-step through the design, construction, and use of this unique 6 Meter antenna. Plans for the original antenna can be found here: http://www.pa3hcm.nl/?p=312. Thank for joining us today. Aloha es 73 de Russ (KH6JRM).  

Antenna Tilt Base-EZ Project (Ham, CB. TV)

If you can't see the video, please insert this title URl into your browser search box: https://www.youtube.com/watch?v=XaPUn9wy_hw&ab_channel=W5CYF%2FTinkerJohn This is post 2372 in a continuing series of simple ham radio antennas. Thanks to "Tinker John" (W5CYF) for this useful antenna accessory. For around $25 and a few locally available materials, you can make a sturdy tilt mast base for your vertical antenna. The homebrewed device will come in handy should a storm arise or nosey neighbors ask questions about that pole sticking up in your backyard. I've used a similar tilt over arrangement for my 80 meter vertical helix.  Out of sight out of mind.  Plus, the tilt over base reduces the chance of wind damage or lightning striking your vertical antenna. Here are some of John's comments: Using off the shelf material and hardware you can build a simple tilt base for your vertical antenna. EZ Project using hand tools and less than $25 in material.
