5-Band Frame Antenna, Part 1

Image
Thanks to OM0ET for this compact, multiband HF Antenna. In part 1 of this 2-part series, we get an excellent introduction to the theory and construction process for this "classic" HF Antenna. If you can't see the video, please insert this title URL into your browser:  https://www.youtube.com/watch?v=VaPikKiLVD4 Here are some comments from OM0ET: The Frame antenna is not a new idea. It was used during the world wars. Due to its dimensions it can be used in restricted space like balcony, portable or indoors conditions. Frame antenna in this video works on 80M, 60M, 40M, 30M and a bit on 20M. I hope you will enjoy this "how to do" film 😉👍 1st part is about the construction. In the 2nd part I will test this antenna. web links to the source: - http://ok1ike.c-a-v.com/soubory/kv_ra...

HAM RADIO: Building a coaxial magnetic loop antenna, part 1

Image
Here's a nice magnetic loop antenna project from Mike (M0MSN). In part 1, Mike takes us step-by-step in designing and building the loops needed for this antenna.  In part 2, Mike will build the capacitor to help tune the antenna. If you can't see the video, please go here: https://www.youtube.com/watch?v=TR7dHQ1fVgo Here are some comments from Mike (M0MSN): Building a Double Coax MagLoop Part 1, why part one well that's because I need to buy a Air spaced Capacitor or make one! So this upload is all about the making of the double loop. it is a simple job but you will need some spacers and a lot of time to get it right. there is NO set diameter for the loops I decided on 1M in diameter and ended up with 94cm but it still works so!!! Parts: 6M of ridged Coax ( something like Andrew Heliax) 15mm 4 spacers (I printed these but you can use PVC Pipe) Variable Air Capacitor to finish the job To get notified of the next upload .click that bell and subscribe.. Cheers Mike M0MS...

Building a Multiband Vertical (Fanned), Part 1

Image
Informative, easy-to-follow tutorial on how to build a multiband HF vertical antenna. Thanks to Stephen Payne (W0KNI) for this portable version of the "classic" fanned dipole antenna.  Stephen uses several 3D printed parts for this project. If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=YMbJzvLesMc This is post 2760 in a continuing series of simple ham radio antennas. Here are some comments from Stephen: In this video I'm going to show you how I combined the fun hobbies of Amateur Radio and 3D Printing to create a DIY Multiband Vertical Dipole antenna system. We will build, erect, tune and get on the air today - so keep watching! Thanks to my QSO's out there - KF6YIJ and KX7TL.

Building a Delta Loop Antenna For The 30M Band, part 1

Image
If you can't see the video, please insert this title URL into your browser search box:   https://www.youtube.com/watch?v=F1wLSUVBPMI This is post 2293 in a continuing series of simple ham radio antennas. Thanks to Gil of the "RadioPreppers.com" website for this two-part tutorial on designing, building, testing, and using a 30M delta loop antenna. In part one, Gil shows us the materials and construction practices needed to bring this antenna to life.  He also describes the mistakes he made in making the antenna--something he corrects in part 2.  The video takes us step-by-step through this interesting antenna project. Here are some of Gil's observations from part 1: "Since my 6m Delta Loop seems to work pretty well I decided to build one for the 30m band to be used with my Spiderbeam 12m mast. Unfortunately I cut it too short. The balun works well. I need to try a quarter wave of 75 Ohm coax instead, just for testing... Note that fed a one lower corne...

The Doublet-an old but good multi-ban single dipole antenna, part 1

Image
If you can't see the video, please insert this title URL into your browser search box:   https://www.youtube.com/watch?v=tA4loiihJwE .  This is post 2247 in a continuing series of simple ham radio antennas. One of the best all-around HF antennas is the multi-band doublet. The antenna is simple, inexpensive, and covers several HF bands with the aid of a parallel feed line and a balanced antenna "tuner." In this well-made video, Kevin Loughin (KB9RLW) presents a two-part series on the theory, design, construction, and use of this versatile antenna. Here are some of Kevin's remarks: "One of the antennas I've wanted to play with for awhile. In this video, we look at the antenna and it's design, and then my build of the antenna. In part 2, we'll look at it's performance and try it out on the air. Link to web site mentioned in the vid: http://webclass.org/k5ijb/antennas/Al...

Jeri Ellsworth, AI6TK, and Amy Herndon, AI6ZU, at Quartzfest 2018 Part 1. Post #1404.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=x7-ttbOaLvM&t=78s. A fascinating and educational video tutorial on how to create a portable amateur radio station for a RV (recreational vehicle).  Randy Hall (K7AGE) dropped by the 2018 Quartzfest in Arizona to interview Jeri Ellsworth (AI6TK) and Amy Herndon (AI6ZU) as they prepared to operate at this annual festival for RV owners.  It's interesting to note how Jeri and Amy worked around grounding and antenna problems to get their mobile station on the air.  Some of the suggestions discussed in this video could be useful for radio amateurs operating in deed-restricted properties (HOAs/CC&Rs).
