PORTABLE IN UNDER 3 MINUTES? NEW JPC ANTENNA 

The PAC-12 vertical antenna is a great antenna. I received mine yesterday. The wire they give you for a ground radial system is around 27 feet. It's a non resonant length for 20 or 40 meters. Plus, the ribbon cable should be split into 10 lengths and spread our around the vertical. Cut five of the wires to a length of 16.5 feet for 5 each quarter wave 20 meter radials. What I did was to make my own radials. I made three each 35 feet long radials and three each 16.5 feet long radials. I spread them out around the base of the vertical and on both 20 and 40 meters my SWR went down to 1.2 to 1 SWR. My reading was taken at the feed point of the antenna. What you did was a quick and simple setup and that's great. My point is by working a little with the radial field you can greatly improve the performance of this antenna. Nice video, glad you posted it. Barry, KU3X/QRP

The build quality looks outstanding. I'd love that tripod as an accessory itself!

Great video made - Thanks folks!

Brilliant! love the JPC-12! and expertly explained too! 👍👍👍👍👍👍

Thanks for this, looks very much like a new and improved Buddiepole.

Its a great wee antenna system , you should get the ground disk which gives you 16 points to mount 16 ground wires , i get 1:1 on 20m no matter where i mount it using the add-on ground disc

The dipole and coils look like an improved version of a Buddipole especially the center connector or versa-tee.

I thought i'd post a little review on the JPC-12 as i'm pretty impressed with it, but can't seem to add a review on the website. I purchased it, as it's quite 'stealth' and suits my QTH situation. I must say, i'm more than chuffed with it's performance. In just under 2 months i have worked 57 countries, with about 470 QSOs mainly on 20m, and receive great audio and signal reports infinately more often than bad ones. "Very strong signal" and "great audio" are comments I have heard regularly. I run the Icom IC-7100 through it, and although i'd quite like an antenna that needs no adjustment to change bands, i require an 'antenna for small gardens' solution. I doubt if adding something like a Diamond BB7V will perform well enough to justify the spend, once I add in a tuner too. It's more efficient on 20m, which is unsurprising, but still performs well on 40m. I've started to work 20m of a weekend, then adjust the antenna to 40m for operation during weekday evenings, given the time of year. On SSB, my logbook includes Australia, Canada, USA, Iceland, Indonesia, Brazil and China, together with very regular contacts into pretty much all of Europe (for some reason, I find it difficult being heard in Greece, although I have worked Greek and Cypriot stations, but impossible to get heard in Turkey lol. I'm hoping additional radials, strategically placed, will help). After the first couple of weeks, I added 12 additional radials (Comet CGW-560 x 2, you'll need washers as the centre ring is larger than the antenna ground spike) and I really noticed a difference. So much so, i'm going to add another dozen, or find a radial plate and install more than that. My JPC-12 is permanently deployed in my small garden, and has so far withstood the windy weather of late, even with the whip extended. All in all, a brilliant product. Highly recommended. There's a picture of it in situ on my QRZ page. M0JYH

I added a LDG RU - 1:1 unun to the base of my jpc12 which helped bring the vswr down to near 1:1 on most bands, only been out with it once at the moment but it's looking quite a promising antenna.

Ok that’s a pretty slick looking antenna.

wonder if an all band coil would work with that

Would hitting the spike with a mallet (eventually) damage the thread?

How does this perform in comparison to the Super Antenna?

the slider is extremely hard to slide either up or down. do you have a remedy to make it easier without breaking the slider?

Did you connect the dipole, and get any results with it? SWR? RX? TX? Anyway, thanks from the left side of the Atlantic!

After seeing this video today, I ordered the JPC-7 with tripod, which I do not see with the US dealers advertisements. The more expensive postage to US is understandable. Some comments have been that the JPC-7 compares to the Buddipole, maybe with some improvements. 73 de W2CH Ray, NH.

How is it under rough weather conditions I.e mainly rain, would any of the parts need to be waterproofed or would it just be good to go to set up as is?

remove the centre coil tuning unit and use only the four aluminium tubes plus the telescopic antenna, reduce the last section to approximately 10cm and you are ready to go on 15m after checking swr...and remove the centre coil and the 4 aluminium tubes and use the telescopic section straight onto the top of the feed point and adjust length for 10m. so all in all you have a quad band portable vertical antenna......super bit of gear, would'nt part with my one now..De EI7IAB

I am surprised someone hadn't come up with that coil tap arrangement decades ago. Its quite simple. Other arrangements that can tap different points around the circumference may provide slightly better SWR, but not by much.

Does the tripod come WITH the JPC-7 or is that a separate purchase ?

is the tripod available to buy seperate ?

How did/would those antennas do on SSB?

Which is better? Something like this or a magnetic loop antenna?

Пользуюсь такой в виде вертикала. Работая QRP, проводил межконтинентальные связи с Северной Америкой, Австралией, Новой Зеландией. Первое, что сделал - купил опционное "кольцо" для присоединения противовесов. На каждый диапазон по 3 настроенных радиала.

Hello, could you tell me the name and model number of the tripod to which the JPC-7 is attached? Thank you. thank you.

Can use it for Cb?

Do you know where I can find these antennas in the States?

Hello, This is Oliver from Quanzhou Neway, May I know Mr.Martin still work for ML&S Martin Lynch & Sons Ltd.？

can these used as base station antenna?

That looks great - 73 de GI8WFA.

What is the advantage of either antenna for portable operation, is one clearly a better antenna.

What is the tripod? Can you post a link?

Does the mast section radiate?

awaitng the start m0kll

I am looking for about your product place lace me a message . When I post this , I am looking for more information no this. Find this at much they run . In for thing have out there
