Great video.... ONE important tip - For a "more durable" tie wrap for exterior/sun exposure, use a BLACK tie wrap. The white/clear wraps WILL deteriorate much faster than the black nylon wraps. The black nylon blocks the sun's UV rays from destroying the nylon.... The next time you are on the roof, place some black tie wraps next to the white ones and you will see the difference in the durability....

Back between 1982-1988 was on the upper channels dx'ing. Had a modified President Madison and 400 watt amp. Collected up some black iron pipe and home brewed a tilt-over tower that stood 84 feet. Started out with a Wilson Y-quad and then built a full 2-ele-quad. Later put up a 5/8th (mighty magnum) wave vertical. Had a ball talking all over the world. The 11 meter band was wide open back then. Retired now. Enjoy watching your channel. :)

Hey Mower Junkie - I just come along your channel and I need to say “WoW”. Back in 1973 - my wife and I had the Realistic TRC-46. I still own it. In the house we used a Yaesu 101 for CB with a Moonraker 4 on the roof. After watching your video - I’m believing you and your wife take a lot more pride in your set-up than I did with mine. It’s always a lot more rewarding when you put your own system together and get the results that you just achieved. To make your own “Beastly Antenna” and get a 1 to 1 SWR - - That’s almost impossible. “Way to go”...

Decent build matey ! I built a 2 ele cubical quad for portable, I could assemble and take it down in about 5 mins, for 10m/11m it was bloody awesome. The boom was square thin wall aluminium, and the spreaders were old army tent poles I picked up at a surpless store. With a 1/4 wave length of 75ohm coax as a matching stub I got a 1.3 to 1 SWR at the lowest point, and it was under 2 from the bottom of 11 to the top of 10.

@freepressright Жыл бұрын
@Luis Perez who can afford to? They're close to $100 apiece anymore. Not worth it for a home brew antenna. You'd have $300 to $400 wrapped up in radiators and radials if you used 102's for the entire build. Compromised radials are the norm anyhow. The Sirio GPE 27 5/8 ground plane has three radials that aren't but maybe 4 or 4 feet and the Tornado 27 has slightly shortened radials. Both perform plenty fine

That looks like a Jo Gunn antenna except that a Beam has a reflector, a driver, and a director. This doesn't. You will find that this antenna will radiate in a figure 8 pattern off of the sides of the antenna so it will get out better from the either side rather than off either end. It looks great and brings back memories when I use to play around with antennas in my back yard in the 80's. Keep up the good work. I enjoy all your videos.

Excellent! Wish you had rotated it 180° during QSO with 1963 Jamaica, so we could hear the received signal drop to below the noise as the side null is pointed at him, and then hear the peak build when it rotates to where it is again broadside to the other station. If you S-meter is linear, you can calculate the front & back to side ratio in db that way. Nicely done!

Like John said this antenna should be directional in the direction the ground radials are pointing. Theoretically it should have less forward gain than the 3 element beam also the purpose of the beam is to give you forward gain eliminating or should I say reducing signals coming from the back and sides of the beam. This antenna has some gain in the direction the radials are pointing and allows you to hear signals coming from all directions it's like having a omnidirectional and directional antenna all in one. If you are building this for cb channels separation between antennas should be a quarter wave apart around 9 feet the coax for the cophased rg59 around 18 to 20 feet on each side 75ohm to achieve a 50 ohm at the radio. 73's...
@ll-bc7ou3 жыл бұрын
I don't want to complicate things but Iam sure some are wondering or thinking about this lol. Rg59 is rather small coax there is also rg6 and rg11 coax more expensive less loss probably handle a little more power but the lenght for each side will be shorter both are 75ohm and not that hard to get it's used for cable systems and stuff like that. For low power or reasonable power stations rg59 is a no brainer already made and plug and play like they say. 73's..

I had a dual polarity Moonraker 4 at one time and was able to switch polarity using the switch box provided with the antenna. I noticed that when the skip signals would start to fade on vertical polarity I could switch to horizontal and the signal would come back up. When it would start to fade on horizontal I would go back vertical and again, the signal would come back up. As the skip signals bounce off of the atmosphere, the polarity will change. That is why it is good to have both horizontal and vertical when shooting skip. Changing back and forth while talking local will not help much. Flat side will normally work a little better for local if both party's are running flat but both stations need to be the same polarity when talking local. Being able to switch polarity on signals that are half scale or fading out is a real advantage when shooting skip. Nice job on the antenna mower junkie.

Just wanted to give you an update on the co-phased antenna. First off I really like this antenna I'm so glad I stumbled across your channel. I got the swr down to less than 1.1 to 1 across the band and this thing works like a champ, I've yet to add a rotor to it, I just have it pointing NE and I've made contact to Canada, Buffalo,NY Cleveland, Ohio, the Carolinas I've even talked to operator's in North Dakota and Arizona. I hope one day to make contact with you using your co-phased antenna design, that would really make my day! Until then 73's friend and keep the antenna designs coming. 719 SE Oklahoma, operator Wally.

I know it's been a year since your post. One question- pointed NE- How do you know what side to point NE? One of the ends, one of the sides? I was thinking if the 102's were on their side it would be directional the way they are pointing with the ground planes being the backside of antenna. Are both co-actions the same length and tied to one end? Got any thoughts about this? Thanks in advance😊 FYI- I'm just south of you in Northeast Texas. About 40 miles south of the Red River. 73's Mr Wizard 101

@brainiac_brian I don't think it really matters which end is pointed in a certain direction. it's not really a true directional beam its still a ground plane but i believe it to be slightly directional To be honest, im really not that smart all I know is it just works. I love this antenna. It is better than the A99 I ran back in the 90s in my opinion . And its pretty tough, been through some 50 + mph winds and haven't had any issues. Sorry that's about the best I can answer you're question

@@MowerJunkie I've had this antenna in the air almost two yrs, it's been through a few Oklahoma thunderstorms with 50+ mph wind and still standing strong. Next days off I'm lowering it down to replace the fire stick radials with SS 102s. Wish I had bought the 102s when they were a lot cheaper, Lol. Also upgrading my coax cable and plan on adding the rotor to it. I've talked all over with this antenna, every time Im asked about my station I always give you props for the antenna design. You're pretty well known, still hoping to make contact with you, I've heard you on SSB but mother nature hasn't been cooperative for me , still gonna try that's my goal to talk to you with this antenna. Love the antenna, love your channel and antenna builds keep em coming. 73s and wishing you well. 719 SE Oklahoma operator Wally.

Wow, Pretty cool on the home Brew Beam for sure! Found your channel through cb radio ghost talk -NY202 channel. We are having a March snowstorm so i am kinda chilling near the fire and watching videos, radio has been dead for a few days now as far as skip goes!

Awesome comparison vid! Now really curious on the radiation pattern of the co-phase. Maybe wider coverage than the Yagi?

For your next homebrew antenna project you might consider building a two element quad beam. Back in 1978 I had an Avanti PDL-2 Quad beam on the roof at about 35 feet that got out great! It would effectively multiply my transmit power by 16 times (4 watts would get out like 64 watts and 100w would get out like 1600w!) What's cool about a two element quad beam is: 1 - It has a shorter boom length than your phased beam in this video 2 - It's a wire antenna, rather than using aluminum elements (although, it does use an aluminum boom to space the elements) 3 - It provides the ability to switch between vertical and horizontal polarization (although, it does require two feedlines) 4 - It provides both gain in the forward direction and rejection of signals coming in from the rear of the antenna 5 - The rear element is totally passive, requiring no connection (the rear element wires are slightly longer than the driven front element) 6 - The wires are bent around the spreaders so it isn't as tall or wide as straight elements, which means it can be rotated in a smaller space A step up from the two element quad would be a three or four element quad. You may recall the legendary Moonraker 4 antennas that were popular in the 70's. They had a reflector element at the rear - like the PDL-2 - then a driven element in front of that and then two passive director elements that further narrowed the beam in front of that. And, of course, there was the big boy beam - the Moonraker 6 antennas that had a 36 foot boom and SIX elements - the reflector, the driven element, and then FOUR passive director elements! The Moonraker 6 would effectively multiply your transmit power by a whopping 50 times! Thanks, for the video!

I also had a PDL2 back in the '90s. Mine came apart and was destroyed during a microburst. The hard part of duplicating this great antenna is trying to find an economical way to fabricate the "orbital" spherical ball skeleton.

@@johnsortore4470 I had a Moonraker 4 in the late 80s that got caught in a tree and mangled the director elements pretty bad. A friend fabricated a PDL-II out of the remnants. To make the orbital elements, he bent the aluminum tubing around the trunk of another tree. Worked great.

@@mstover2809 I've tried to bend some but they always kink. With the new technology of 3D printing, someone should start making the PDL2 hubs.

Usually when using the 102” you can usually get a better/ lower S.W.R. If you use a 6” spring on each 102” so it makes your overall length 108” each
@MowerJunkie3 жыл бұрын
The match on this antenna is almost flat, even with extra power. Springs would only add more weight to the antenna. Thanks for watching, 73's from 151 SC.
