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.
Unit 63, I got the measurements you listed in this video, bur what is the distance between the elements on the boom if you dont mind me asking ??? 672 SW Kansas 38 LSB I sent you a EMail also
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.
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 RU-vid!), it's rather interesting, and clever.
@arconeagain Good morning thank you for the reply I've done a little more tweaking it's a 1.2 and it's flickering 1.1 but as is it's swr 1.2 R=49 X=9 OHM 50
Yagi antennas are awesome! Good job on the build. What's the bandwidth like on it? I thought about building one a while back and will have to do it. 1 reflector, 1 driven element and 2 directors make decent gain as well.
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?
The fence is gone and I'm getting ready to paint that side of the house lol. That's a pond with nice bass, bream, cats and crappie. I insulated the ground over the U-bolt with coax outer insulator.
@@unit63sc17 Be careful when you do that painting! I heard of one guy who fell off the ladder and almost got hurt, but fortunately he landed in a chair which just so happened to be in the radio shack in front of the radio. Imagine that!
Always nice to see a Diy Beam & good Swr video .....Wow,....1/8" wall thickness Continuous length elements is Really thick !! ...Not exactly best structural design (thin wall telescoping less drooping & better attributes) but maybe more affordable from Local metal scrap yard ? Amazingly Good Swr from simple Direct Connected coax....Thx for video..
I worked on cell sites to several years ago. Ive got about 40 of the silver plated n connectors and i used the lmr400 i had left over on my beam lol its nice to get free parts. good job on the antenna. It’s been a while since I’ve talk to you. 73s WR125 Ky
Been here since 84 views... I dunno why RU-vid recommend me this... Interesting... Looks like Owl/Eagle Vomit... Looks like Squirrel Fur... Or probably Rare Mold/Fungus from specific material... Never seen those stuff... Hopefully it's not Harmful... Kinda reminds me to Cluster of DaddyLongLegs or Worms...
Hi Paul. That's crazy. Hope the lab results come back and tell you what it is. But it sure looks like hair. That's mad. This is why we Always fed our dog the food we used to eat and she lived to a Great age with no trips to the vets. Great talking to you the other day. Sounding great as usual. 73s. WR456🇬🇧 Rich.
Hi Paul. Great talking to you I believe on Saturday/Sunday. Your were sounding top shelf as always. All the best my friend. Hope we can speak again. 73s WR456 🇬🇧 Rich.
Great job on that antenna, thanks for sharing. Good talking to you last night from up here on the mountains of Montana. Operator Steve-431 Yellowstone Valley Radio.
So, after 1 year, how is the antenna doing? You like the performances of it, what are the specs DB gain, Fb gain .......did your try an antenna program to see the lobes ????
The antenna is fantastic. I don't know what the DB gain is on it but it's got to be real good. I haven't tried a program to see the lobes but it has great side rejection and is a wide beam. This thing rocks
