I'm considering changing antennas and have looked at the Jo Gun series. I like the looks of the either 3+3 or the 4+4. Will either of these work with a tv rotor as I'm doing now or will they require a ham IV. Also How well are these built in both strength and reliability. What kind of performance can I expect compared to a M104c on the flat side. It will be mounted 35 to 38 ft.
Thanks |

Your m104c will have more gain than the jogun 3+3, and be roughly equal to the 4+4. Of course, the Jogunns have dual polarity, and they are built VERY well, you'll be impressed with the durability if you get one. I would think you would need a bell housing style rotor to run it, but you might get by with the TV rotor for a while. Probably easier in the long run to get a Yeasu or Telex type rotor and be done with it.

Peddler.....
Jogunn antennas ARE well made past that ....
1) They have the same gain as any other beam
REAL GAIN of a 3 elm beam is about 6DBD and a 4 elm maby 8DBD.
2) They have no audio gain. NO SUCH THING
3) They cost a bunch more. BUT THEY MAKE YOU THINK THEY ARE WORTH IT.
Jogunn has never published the E/H planes fot there antennas NEVER shown a single repeatable measurement on there gain or audio gain based on know methods just sales hype. They pray on CB users who BELEVE what they read from them..... in short i'm still waiting for the FIRST measurement showing any antenna producing the level of antenna gain THEY CLAME or any AUDIO GAIN be it JOGUNN OR ANY OTHER ..... This must be traced and repeatable to a known standard like NBS. So if you buy one dont expect to see much change except in your wallet. |

Bruce there you go Jogunn bashing again. The most important part of any beam antenna is that they 1. stay up there, and 2. stay together. The technology is what it is, and 4 element of similar proportions will perform close to the same. I had a maco that came apart in the winds here in NM My Jogunn 4 element is up, and working fine, and has been for a while now. I Love the performanc, and durability of the Jogunn, when I buy another beam it will be a Jogunn, only a larger one!! Highlander, I dont think I would trust a tv andtenna rotor to turn a Jogunn over a long period of time, it is a heavy antenna, and the starts and stops would probably roach a light rotor.

Highlander shop around if you buy a jogunn just keep in mind a 3 elm beam is a 3 elm beam no matter who makes it.
O BY the way pig 40+ contacts on 6 SSB and not one jogunn at my QTH! |

Bruce, hey I wasn't saying that the Jogunn is anything special RF-wise, I was just saying that they are built extremely well. Enough to make me pick one over a similar gain Maco? No, but I can see why some people would feel it was worth it.

My problem is and always has been JOGUNN's LIES.
Not buyers or thoes who like HOW they are built.
For 40 years i have used hygain or cushcraft and NEVER had one fail in the wind. TRUE most have been on 6 or 2 meters but i also had a 4 elm 10 meter one in 2000..... it was too large to remain within my setbacks and i sold it. The newer cushcraft antennas are a bit pricy but much better than the ones like my stacked 11 elm in the 1960's To each his own but but i cant see watching any company make sales buy openly lieing. With any luck he is my mid 60's station with stacked 11 elms...............

I have to agree with both Bruce and Highlander.
Bruce has good merits with the fact that the JoGunn people are giving you specs that they see only in their dreams. If these claimed specs were true, they would be the best designed/built beam antenna the industry has to offer..bar-none. Not to mention the fact that they would be widely copied. (Other companys only copy the good or best selling stuff).
And what Highlander is saying in regards to their strength and durability, well, that you can take to the bank my friends because, that they are....STRONG!
In my opinion, if the JoGunn people would have been honest about their specs right from the beginning, I believe they would have sold far better than what they have to date. The trouble was, they were caught in their lies (inflated specs and audio gain) way too soon. And over priced!
But, that's what happens when some company comes along and under estimates their consumers. And speaking of honesty in this industry, Texas Star Corp is about the only one I can think of (at the moment) that will tell you like it is. I have NEVER seen inflated-claimed specs from them. When they say that you will get X amount of watts output (into a load) using X amount of watts input at X volts, well, you can bet your donkey on it.
It's too bad that most companies have to out-right lie about their product just to make a sale. That just tells me that they don't have much faith in their own product. Sooner than later, the truth will come out anyways.
OK, I'm done crying about it now.

That is my gripe you ARE NOT getting what your paying for PAST good construction. Antennas are the MOST LIED ABOUT thing a radio guy can buy.
I would like to see a STANDARD used and the companys REQUIRED to PUBLISH the field tests under these standards ( LIKE NBS )...... GOSH GAIN WOULD LOOK SO PUNY!
I get a fair amout of e-mail HUNDERDS A DAY 99% junk... some from CB's asking me what to buy.... I'm not good looking like Ann Landers but i do my best to answer the questions MOST are short with antennas ....#1 question by far.
As far as what I use well i build when i can modify if i have to .... Now since they realy dont matter since they dont realy make cb antennas it's not a major line to them ....... I like and use cushcraft they have come a long way since the 11 elm beams of the 60's ...... they make a good HAM antenna now. |

Yeah, they lie, it is advertising, everyone in todays market lies. That is what makes it so tough to buy anything radio related. You almost have to wait til someone else buys a radio or antenna, or whatever, and see how it operates in the real world. That is why this forum is so invaluable, helps to sort out the junk! |

I'll 2nd on Pig's suggestion to use a heavier rotor. I had my 5-star up on a 50 ft. tower using a Channel Master 9515 (heavy duty). Heavy Duty in the sense that is IS heavy duty for a small rotor. Anyway, it got pushed around wayyy too much using that rotor. So I purchase a T2X and that worked fine. |

Let's add to the discussion;
A Gizmotchy beam of the same configuration,,,
A 3+3 or a 4+4. these are lighter. How well built? |

Peddler,
Nothing to add.
Been a Dealer for both Joe Gunn & Gizmotchy Antennas over the years and Owned & Used both brands of Antennas over the years.
The Gizmotchy Antennas (Since 1964) have always surpassed the Joe Gunns in Performance and Quality.
This is just my Personal Experience with Both Products as a Retired Dealer and Owner of Both Products for many years.

THAT'S more like it I went and looked at the web page for gizmotchy/gain/ price are in line with what i would expect.
Nice looking antenna seems well made.... HOWEVER..... how much AUDIO gain does it have? ....... ( only kidding) LON.

hey peddler, if you just get a 3kw amp, you'll save the hassle of the rotor purchase, burnout, slippage, etc!
boy this is just like ch 14 in the old days.
at my present 20 , neighbors would just love me if i put up a beam, why not build your own? use wall thickness of tubing to your own specs, etc. had a maco y-quad in mid 70's, when a winter storm mangled it and mast, i recycled mounts, purchased tubing, homemade a 3 element quad(all that would fit on property) put on a 40' tower. worked great- 2 or 3 years later maco came out with the comet(i was about 14 or15 yrs old-learned what i needed from electronics class in school and reading books from library....do they still have them? books?? libraries??? ah, modern technology! |

Pat;

Thanks |
