Antenna Autopsy 3 : Kenwood TH-F7 Handheld Antenna Fix

Antenna Autopsy 3 : Kenwood TH-F7 Handheld Antenna repair, this is a quick video showing the repair I made to a Kenwood TH-F7's antenna, these antenna's are pretty much the same as all the other top-end mobile (hand portable) antennas I did SWR this antenna but unfortunately I did not capture the test on camera (next time) also please note that on watching this video back I noticed that the value of the capacitors are 3.9pF.... lol
Hey why not look it up and see for yourself I'm not an expert on these matters just a guy that is giving it a go and sharing my experiences.
Hope you enjoy...
Just for fun

First time I've seen a duck being repaired, I normally throw them out with the packaging. Good old fashioned fix and reuse, I'm put to shame! 👍

Love watching your videos

[@mike-M0MSN]

I appreciate that!

[@allanjones4283]

You've got some serious patience Mike.... I would have turfed it for a new antenna! 🙂

I would not risk my wife walking in and seeing me do that on a worktop lol.

Mike literally stole his wife's kitchen worktop to build his ham shack table. I think his penance was a brand new kitchen!!

Good job Mike.

Next time Mike.. Acetone: "An effective solvent for removing super glue" according to clever Google

Thanks Cal..

Nice fix. That common for them rubber Duck antenna to break. Super glue was invented by a failure of trying to make Lenz for gun scopes during WW2 US military . This was a failed attempt but they made a note of it. Years later was looked at again and found that it stuck to everything and after palemeratiosn it had great streangth of holding. Then was marketed under the super glue name . Their is several video's on birth of super glue . 73

Great information thanks. :)

Can’t wait for the next episode of “Mike nearly glues his fingers to stuff”
Also 4:28 in… Do you let Laurel rest on yours though?

Impressive

[@tomtierney2624]

It is amazing how many antennas have these very low value capacitors in the line. Typically less than 10 pf. But capable of a very high voltage. 2.2-3.7KV. Nevertheless, they keep failing. OK, not in this example which was caused by a physical break but just generally. Take apart a certain white stick antenna covering 70/2/4/6 for example. Or a dual band Uda-Yagi beam for 2 and 70. The caps are always the cause of the failure. G0JSV

[@mike-M0MSN]

Yep, totally agree, :)

What make superglue is it Mike ?

Not a bad idea..

interesting. My Yaesu VX6 never seems to work...ie I can RX but never TX. Hmmm

[@mike-M0MSN]

Worth an antenna swap just to test!!

[@robertbolger2740]

But, why did it break?

[@mike-M0MSN]

Not sure, maybe it was dropped at sometime in the past, could be just age...

[@bitemykrank1970]

Buy a Chinese antenna for it, who wants decent SWR anyway?

Hello from Argentina, in 5’26” minuts i hear something like a pedo, that is correct?
