I have being running drive feed antennas for more than 20 years now, I think you need a ground from the ground side of the element to the boom of the antenna to have it working properly. #7 Jamaica Click Click bom bom.

Ahahahaha oh really dude, It's not neat or nice, It's so poorly construct, so where is the gamma match ??. It's all twisted up and down, Honestly I make far better home made antennas down here in Jamaica west Indies with the little tools I have, Damm, !!

Well it's been up 3 years and boasts a 1.3 VSWR on 11 meters, has excellent rejection on the sides and rear and I've talked all over the world. Not to mention 3/4" dia, 1/8" wall thickness elements, single section ASTM aircraft tube Aluminum. This thing is a rock. I know you're jealous but you'll get over it! 😭😭

I was running a vertical A99. There is no comparison. If I'm giving another station 7dB on A99 I'm giving the 10-20 dB on the 4 element. The receive is 50-75% better also. And most of the time much higher signal to noise ratio.

Some of this is okay as far as educational steps go, but my advice to everyone is to skip ahead and just build an LFA. I'd go with a 4 element, it will blow any of these, and most other antennas, out of the water.

@arconeagain

A resonant antenna has no reactance, and then there's mutual conductance. Also, there's a common misconception about what the capacitive side of a gamma actually does, this predominantly coming from hams (I'm a CBer). Do yourself a favour and look up how a gamma really works (not on KZitem!), it's rather interesting, and clever.

Now that you've finished playing around with your 'antenna', your wife says she'd appreciate it if you'd fix the fence and paint the garage doors! 😁 But seriously, the only thing I question is how long it will be before the pigtail attached to the ground side of the driven element (6:29) shorts out on the threads of that u-bolt. You know, with all that rotating and hurricane winds and stuff. Last question: Is that a river or a pond in the backyard, and are there any fish in it?
