New Antenna

[Kale Cavel]

Mole, I may not have worded it right but from what I see here is that the customers are telling the dealers that they like the open coil antennas better than any other kind. This is getting back to Wilson and they are going to work on finding out why. I don't know how else to put it. I have multitudes of customers call me all of the time and tell me that they have been in the C.B.hobby for years and never had an antenna to perform as well as the 10K. Dont you think that after all of these years of trying several antennas in the past that they don't know what they are talking about? What kind of answer do you think they would give you if you asked them if they thought they have achieved anything by switching to a 10K. I don't think they would tell you that it was just an imaginary nature. We're picking at this. I did not use the ARRL handbook for any of my antenna designs. I didn't use any formulas or equasions.

I test everything in the real world. I don't market anything that don't perform well. I"m set up with equipment to do ALMOST anything I want to do. My goal is to build the strongest performing antenna for 11 meters. Just about everyone likes a shorter antenna. Mostly truckers. One of my dealers told me that a lot of his customers are buying another open coil antenna instead of the 10K because they have a shorter shaft. The reason I didn't have a shorter shaft before now is because when I first started building the 10K , the coil fixture I designed was much bigger than it is now like some of the bigger open coils out there right now. Anything under 9"shaft would reflect on some vehicles like vans and Subs. .After the smaller design that I have now I never gave it any more thought until my dealer brought this to my attention. So I went to work on it. I'm not posting this to advertise the 10K but to make a point. I now have a new design of antenna that is on a 6" shaft and a little bit bigger coil and the coils are spaced a little bit wider apart and tunes at 5 feet and under and is proving to be better in performance than some of the other 10K's.

For example, at 1kw at 1-2 watts reflect, I was talking to "Burns" south east of Tyler Texas 120 miles away. I know what everyone is thinking. CONDITIONS. It has proved itself more than once. I have several of these antennas under test in the real world right now. The point is that the DESIGN of an open coil antenna WILL make a difference in the performance. I don't know for sure what I did to improve this antenna. It could be one of three things. It could be that the whole antenna is down closer to the ground plane. It could be the bigger diameter of the coil or that the coil spacing is wider. I don't know much about ham antennas but I don't think the design of the antenna has anything to do with the loudness of the teansmit. Repeaters don't have anything to do with loudnes. Am I not right? BUT antennas designed for 11 meters will. Doc wanted me to prove to him how a coil had anything to do with audio. I really don't know of any way to prove it on paper or with any formula of any kind. I just know that on an eleven meter coil antenna the design from one antenna to another will make a difference. I don't know for sure about any other coil antenna but the 10K coil design has a bow tie radiation effect. From some tests in the past it keeps more of the signal on the ground. TEST! TEST! TEST! Thats what it is all about. You can test it with RF equipment or you can test it in the real world. I have done the best I can and still "TESTING" to make it better. Kale

hngryjack, yes, I do I built two 22's for 4040 mobile on the west coast. He's dead keying 15kw into them. I can build anything you want. Kale

Justin, I've tried to answer this 3 times and the computer keeps knocking me off line so it will have to be short.

This is taking us back to what was said about coil antennas. A "coil" is a "coil". There are some open coil antennas on the market that use flat material and space them close together. RF likes the straightest path possible. By spacing them close together limits them to being the straightest path. Not much but some. There is an antenna on the market that has very close spacing between the coils that is popular for high reflect and hard to tune. I would think most everyone knows that reflect will hurt the transmit and modulation of an antenna. I think if the cover was removed and the coils spread wider on a Wilson antenna it would perform much better.

I can't understand why anyone would pay $400 for a radio and then hook up a cheap top loaded antenna like a fiberglass wire wound antenna to it. I would think a cheaper radio and a good quality antenna would be a much better set up.

The audio DOES come from the modulator section of the radio. Why kill it with a poorly designed antenna? As far as giving it more deviation on FM, no, as long as you are talking on the same frequency.

hngryjack, The 10K has been hit at 20kw and not arced. Lumberjack might need to check the tuning of the antennas to see if there is any reflect. I sent 4040 mobile some that is spaced wider just in case. My # is 817-790-6239. Kale

freecel, Predator10K on the label of every 10K antenna has nothing to do with how many watts the antenna will actually take. That name is a name that me and my late distributor named it back when I first started building the antenna.

Here's how it happened. Bill, my distributor and I would meet every week at a Waffle house. I would take him 10 antennas every week. No more and no less. That's all I could build in a week back then. He sold amps, radios, antennas and other radio equipment. The most popular and best seller was a Predator amp. My antenna didn't even have a name for a long time. Bill said,"we need to name this antenna. What do you think we ought to name it". I said, "I have no idea". Bill said, "What about Predator"? I said,"I guess so". Then he wanted to add 10K to it. The number 10 comes from the number of antennas I took him every week. Week after week after week. The letter "K" is the first initian of my middle name. It never did and never has had anything to do with how many watts it would handle. I just know that there are a lot of big riggs that are saying they are putting 15kw into them and not warming them up. 4040 mobile said he is dead keying 15kw into two 22's on the Sub and he uses Bird meeters. Barnyard Bird, here local says at 15kw the coax warms up a little but the antenna never warms up. He goes by Bird meeters. Don't put me on the spot. I'm just going by what some people say that are running the 10K. Kale

That's a cool story, Kale!

LOL, that's a cool thought UK

Still working on it, the last thing that we just did was actually take VERY PRECISE measurements of the antennas that Kale had sent to us in an antenna modeling program, and some testing might be done at an actual "antenna range." The results will be ready in about a week, as Kale is sending us one more for evaluation, of a different type. We want to make sure that when we come up with the results, that they are accurate, and from a few different engineers, and a few different computer antenna modeling programs to assure accuracy. We are currently in the process of testing the Wilson 5000 as well.



Take care,

Jeeeeez, i think i read all the posts in just under an hour ! <img src=http://www.wwdx.org/smilies/posticon34.gif ALT=":34">



Anyhow, i picked up a lot of info there, I have a Monkey Made also, the MM5, and yes, am having a little trouble tuning it.



First off i had to drill the brass stud in the stinger section of the shaft, this was fitted to prevent water ingress into the shaft. The stinger now moves much freely facilitating more convenient tunning, i think the stud should have been fitted in the lower sections to protect the mounting assembly.



I have tried it on a 1mtr by 1mtr aluminium plate on the roof bars, but not grounded to the vehicle, i can get a 1.3 swr but bandwidth is to say the least.....crap ! 2 ground straps to the body helps but the overall length is then shorter, around 5ft6", still with poor bandwidth. I guess i need to play a little more with grounding the roofbars and plate to the body.



It looks solid enough, but needs water ingress protection at the stinger/shaft end. I got this as it was more available via ebay at the time.



Kale why dont you set up a few predator auctions on ebay, ill buy one straight away.



UKMuddock & Kale i sent you a message on ezboard please take a look.

Kale, "no gain........no pain!" <img src=http://www.wwdx.org/smilies/posticon24.gif ALT=":lmao">



I tried getting one off a ebay dealer and they said it was a substandard antenna, jeeeeez, i read all the feedback on here and i didnt even waste my time emailing the guy back. I bet he has never even tried ! Kale keep up the good work, feedback speaks volume.
