Build a multi-band dipole antenna

Image
Here's a simple, one-day antenna project that will give you coverage of the 40, 20, 17, and 20 meter Amateur Radio bands. Bob (KK4DIV) takes us from start to finish in this antenna building effort with material easily gathered from your "junk box" or from the nearest building supply outlet. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=cQfj9879K_c Here are some comments from Bob (KK4DIV):   I built a multiband dipole that will work 40, 20, 17, and 10 meters for ham radio. An easy project I was able to tackle in one day. Calculations for the wire lengths can be found easily online. I used a program called N2IMF antenna I downloaded from hamuniverse.com that will assist in dipole wire length. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

Making a Doublet Antenna SMR Style

Image
Thanks to Callum (M0MCX), the "DX Commander", for this intriguing and refreshing doublet antenna project.  The only sounds you hear are the normal workshop noise associated with any construction project.  Callum lets the actual construction take center stage. Follow this steps in this video and you'll have a beautiful, efficient, and durable doublet antenna for your ham radio station.

Watch me make a doublet antenna for a ham radio start to finish. Using 450 ohm balanced feeder, DX50 antenna wire and a custom doublet centre. Super-fast 4-minute video currently under edit. Will upload soon. Want a doublet centre? Search Google for "dx commander doublet centre" and you'll find it. Callum. More videos: ▶️ https://youtube.com/playlist?list=PLc...

How to make a HF Rain Gutter Antenna

Image
Thanks to Gerald Glery (W6IWN) for this clever "Rain Gutter Antenna."  This idea should help radio amateurs living in deed-restricted housing get on the air. Gerald takes us from start to finish for this "stealth antenna" which blends in totally with the local home environment.

Do you live in an HOA? Maybe this is the antenna for you! ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Using a drone to put up a HAM Radio dipole antenna

Image
Thanks to the "Human Geno Project" for this clever way to install a dipole antenna.  It was just a matter of time before someone used a drone to position a ham radio antenna atop tall structures such as trees. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=U5H_jJJHMiA. Here are some comments from the video author: Instructional video for how to put up a HAM radio dipole antenna using a Mavic Pro DJI Drone with a servo motor to deliver a payload. We used this setup for Field Day contest. Including a link for the servo motor: https://finish-tackle.com/product/mav... Also, you can buy them on ebay for $60 ----- Thanks for joining us today.

Multiband EFHW Base Antenna with 49:1 UnUn

Image
Here's another great multiband EFHW antenna idea from Paul (OM0ET). The key to the success of this antenna is a home made 49:1 UnUn using a FT-240-43 Toroid Core. Make one of these antennas for your home station or for emergency/portable operations. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?app=desktop&v=z-_2aBqcjI8 Here are some comments from Paul (OM0ET): CORRECTION: Toroid core is used FT240-43 (not 140-43) My new home made Multiband End Fed Half Wave Antenna which has been designed mainly for 40M band (7MHz), but this antenna tunes also on 20M-15M-10M without any traps or additional coils. This antenna is made for 100W RF input power and is 19,129m long. SWR on 40M band is 1:1.1 within the phone section and less than 1:1.5 within a whole band. The 49:1 UNUN box is weather proof and all holes for components I drilled were sealed against the water. On the end of the video you can see also an extre

10 Meter Ladder Line J Pole Antenna/Build and Test

Image
If you want a simple, easily-deployable 10 meter antenna for both home and portable use, please consider this 10 meter ladder line J Pole from Steve of the "Ham Radio Portable video channel." Steve takes us step-by-step through the design, construction, and testing phases of this versatile antenna.  Make one for your Amateur Radio "go-kit" or for a dedicated 10 meter antenna at your home station. Here are a few comments from Steve: Easy to build 10 Meter vertical antenna. A start to finish antenna build of a ladder line J pole antenna cut for the 10 meter band. I also follow up with a few of the contacts that I made in the ARRL 10M Contest. An excellent antenna for local ground wave communication or chasing DX. ----- Thanks for joining us today.
