Old and unwanted extension leads are one of my favorite things, exactly for this purpose...

This is a great DIY . Love it . And being a ground plane instead of dipole . You don’t need a Balun . And able to angle the ground plane to bring the impedance closer to 50 ohm . Love it

Thanks for sharing. Its amazing how a good antenna can be made on the cheap. I think a lot of us over think the hobby.

Wooohoooo! Fantastic mate. Smash those main plugs up, and you've got the perfect wire for any length antenna. Happy building mate. Cheers!

I collect recycled wires from construction sites and recycling centers, focusing especially on leftover old cables. I then use these cables to build a wire antenna and use twogether with balun(s). These antennas have been successful in my projects." , thank you very much for your video, - G7UNF

I am in the process of building my antenna and I have some questions about when you deployed it. It looks like the feed point is about 6 feet or so off of the ground. Is this correct? How did you connect the radials to the ground? Are they roughly at a 45 degree angle? Thanks
@thehamjazz

Hey Richie, thanks for your comment buddy. The feedpoint is roughly 6 feet off the ground, and the radials are connected to string, and then tied to battens in the ground. So they are elevated radials, and need to be at least 2 feet above the ground at the ends where the string is connected... the radial angle is about 120-135 degrees from the feedpoint downwards. Are you familiar with Greg's (KJ6ER) "PERformer" aka "PREDator" antenna set up? This is essentially that, but the radiating element is wire from the extension cord instead of a stainless whip. Happy building mate! She's a great antenna. Wooohooo. Cheers

Thats fantastic well done, I was going to build a T2LT for 11 metres but thinking about this method instead. I thought the radials would have to be the same length as the vertical radial, Could you please give me the lengths for the 11 metre cb radio band. 73 Daryn (UK)

Hey buddy, thanks for tuning in. Absolutely! So for 11 meters, let's say we go for the middle channel 20 as the most resonant spot? So the frequency for channel 20 is 27.205mhz. This is right in the middle. Ok so the math for that is 234 divided by 27.205 = 8 feet 7inches or 2.6 meters for each of the dipole lengths mate. So I would suggest starting at 2.8 meters or 9 feet. You can always trim them down. Let me know how you go mate and feel free to reach out to me if you have any other questions. My email is va7bix@gmail.com cheers!

@thehamjazz

Hello Francisco, thanks for watching the video and your comment mate. The coax length I use is 25 feet, but I have also used this antenna on 15 feet, and as for a balun... are you referring to a choke or something like a 9:1? I do use a choke for RFI, but not a balun as the antenna is resonant. Happy building my friend! It's a great fun antenna and works great. Cheers

Out of interest, how long was the cord? Looks like a half wave as presumably were the two radials.

Good morning Roger, the extension cord is 3 meters, or 10 feet.... I salvaged the full length of the cord and folded a few inches back on itself. So the vertical radiating element is 9' 8" and the two radials are 77 inches. Depending on the height and environment, you might need to adjust this to accommodate. Thanks very much for your comments mate and have a great day. Cheers
