Repair of a Diamond CP6 antenna

This is a video from the repair of the first trap of a Diamond CP6. Commentry in Dutch but annotations in English.
The first connection on the coil was broken in the first trap due to torque on that section. The coupling to the outher sleeve was also broken and repaired. I also improved on the mechanical construction by adding some pop-rivets. After testing the antenna performs as before.

Dear Stan, after 10 years your video is still useful, I first watched at it when I bought my used CP6 antenna in 2014 and I noticed that it didn't tune at some higher frequencies. Watching to your video I relaized that the central screw of the first trap is a Capacitor connection and that in my antenna it was missing. So I added the srew and the antenna worked for long time. Now after few years I tested the antenna and It doesn't tune to any frequency, it starts working at 50Mhz!!! Sign that after the first element all the rest is probably disconnected and probably I have to adopt your solution. When the weather will help I will go on the roof and I will dismount the antenna and will make you know, but for sure it will be something you showed. Thank you for all. Antonio (Rome IW0FCI)

Bedankt voor deze video , mijn CP6 had dit probleem in de 40 meter trap 73's Ger

@2e1ays Hi Paul, Thanks for commenting on the video. I hope you could understand what I did to improve on the construction. I agree with the fact that the CP6 is a good antenna onces the mechanical imperfections are improved. The CP6 is now working like a dream and the owner is very pleased with the results. 73, Stan/PD0LUR

All, if you're not seeing the English annotation boxes pop up, check your settings. You may also need to add a browser add-in (like I did) to retrieve the annotation information. THIS HELPS GREATLY.

Thanks for this my CP6 had taken a good battering, so i opened the first trap it was intact but i added the extra rivets and used rivets to reseal the trap. That part of the CP6 is very strong now and the antenna seems to cope better in high winds now

[@snuitje100]

+simon markwick good for you! I'm happy for you that my video helped making your CP6 a bit more rigid.

[@sbudiwibowo]

Thanks.. because of this video I could repair my cp6s

[@sarahjrandomnumbers]

Just had to repair my 40m trap on my CP5H, this helped a lot. Thanks :)

[@snuitje100]

Thanks for the compliment. Glad it helped you. VY, 73 Stan DK2CA/PA8C

[@starman316]

excellent video, my cp6 had the issue where it broke the connection in the first trap, now all fixed :) thanks for the video.

[@2e1ays]

Hi I had the same problem in 2005 and ordered a new 40M trap from the USA, Cost in total £100. Since then me and some friends have had the same problem, we did the same repair back in 2006, and not had any problems.a friend also bought a new CP6 and we had to do this repair befor he could use it. Very poor designed but a very good antenna if you have limited space. Best 73's Paul 2E1AYS

[@snuitje100]

My pleasure. Thanks and I hope it's clear now. The antenna is fully operational again after the repair and the mechanical construction is drastically improved. One comment to make is to make sure that the weather protection on top of the traps is sufficiently so no water is entering the traps. 73, PD0LUR

Hi all...cp610 is same problem defekt trap....soon we Will try to use your so good film to Help me and some odder radio boy here in Bornholm island...thanks for your support. 73 OZ5 JD

Ik heb een paar maanden geleden een tig jaar oude CP6 overgenomen voor weinig welke niet stuk was op 2 popnageltjes in de 1e trap na. Wel alles vertevigd en hopelijk gaat ie nu snel het dak op. De kennis van dit filmpje gebruikt. Ik hoop dat het geholpen heeft. 73' Marcel PD8MJW

Nice video. I have a problem with my Comet H-422 with the SWR spiking. I need to take it down and do a complete overhaul of it and I had no idea how to remove the traps or what to look for but this video helps. Thanks.

[@snuitje100]

@starman316 Glad to hear that the video helped you out. You now have a proper working antenna again at minimum cost. 73, Stan/PD0LUR

[@snuitje100]

@kc7fys Sorry OM I don't understand your question. What do you mean with "What model is it?" The aerial I fixed was a Diamond (aka RF Parts) CP6. 73, Stan/PD0LUR

[@sugminbajstolle2016]

Good video, thank You ...

[@snuitje100]

@24nov67 Unfortunately the design hasn't changed. However that doesn't mean it's a bad antenna. Problems only occur if there is to much mechanical stress on the bottom part of the antenna. If you want a multi band antenna like a CP6 you always can improve the imperfection by following what I have done. It won't alter the electrical performance but mechanically it's a major improvement that will lengthen the life of the antenna substancialy. I wish you every success in making the right decission.

[@snuitje100]

Sorry for the Dutch comment on this video. Meanwhile I have added annotations in English so that it will be more clear on how to go about repairing the aerial. However, a good way to learn Dutch! hi TU for the comments. 73, PD0LUR

Parabéns amigo pelo vídeo antena

[@G6EJD]

Hi, thanks for posting this informative video, I have a Cp6 and have a fault, how did yours manifest itself, mine has failed to tune on 15M. Did yours fail on all the bands? Symptoms?

[@snuitje100]

The problem with the antenna was that it could not be tuned to any band. It was caused by heavy wind gusts and that made the coil connection break of it's connection. I assume that with your CP6 the 10m band still works but everything above 15m doesn't. If that's the case open up the first trap and you will probabely find the problem there. 73, Stan/PA8C

[@electrojo679]

Hi Stan and many thanks for the informative video. One question related to the actual performance -resonant f of the trap- have u measured it with a dip meter or VNA, or you just put it back in place and check how the full antenna system performs? Many thanks again!

[@snuitje100]

Thank you for the compliments. Nothing was really changed after repair of the first trap, nor number of windings or length of the wire and connection points. After completion of the repair and placement of the antenna i have performed measuments with a MFJ-259B analyser and everything turned out to be perfect.

[@JCHaywire]

@kc7fys I didn't know the model of my OWN antenna. It is similar to this one. I discovered it's a Maldol HS-680S. Sorry to confuse you. Best 73, Jonathan KC7FYS/7J1AWL

[@JCHaywire]

My Maldol is this design, but it has 6 rigid radials and five traps on the vertical element. What model is it? I cannot find the manual. It's not exactly a CP6. It has only one capicatance hat.

[@Radio_Militar]

Hi, thanks for the video, i have this antenna and the coils are ok, but I have 3 of SWR in 40m and I don't know what happened. I have dismount the antenna, clean and mount again and I have the same problem. sone one can help me? thanks 73

[@thomaswana7428]

Seems KZbin removed Annotations altogether in 2019. So this video is basically useless if you're not speaking Dutch. Can you upload a transcript?

[@24nov67]

Are they still like this or has diamond sorted out the problem? i was going to get one but don't like the idea of paying £300+ for an antenna that has design problems.

[@wolrab]

Very good have had the same problem but how much better it would be in English

[@rodrigofernandessp]

entendi tudo

[@DevinGanger]

How did you get the trap open? I have a CP-6SAR and it looks like the aluminum tubes are press-fit onto the plastic ends and then dimpled to hold them in place.

[@snuitje100]

With a small drill you drill out the dimpled Aluminium. Then when you mount the sleeve use small parkers.

[@DevinGanger]

@@snuitje100 thanks for the quick response. Your reply helped me realize that I was missing the annotations!

[@DevinGanger]

@@snuitje100 How did you determine this trap was the problem? This is the bottom-most vertical trap, correct? Did you need to do this (or a similar) fix to any of the traps on the radials?

[@snuitje100]

@Devin: the antenna couldn't be tuned anywhere so the most logical place to start was the first trap.

[@reydelnavarro]

what???

[@blackscopezzz1235]

als?s

[@teaker1s]

subtitles are gibberish

[@backyardbasher]

so you can type in english but not speak english ? watched first 30 secs then stopped it, useless unless you speak dutch

[@snuitje100]

Maybee you can enlist yourself for a crash course Dutch??

[@sugminbajstolle2016]

I'm from Sweden.. captions was good and I did understand quite much of the dutch words too. :)
