This is the Chelegance MC-750, which I have, and LOVE. It's my main POTA antenna. With my FT-891, it's pretty easy to just slide the antenna to the appropriately marked spot - and get on the air. Minor adjustments maybe, but no big deal. I've been primarily on 20 meters and have made contacts all over the west (I'm in the Reno area) and even some back east (IL, IN, WS). The only issue I have out here in the desert is rock hard ground. I sometimes have to use my drill and a foot long 'auger' to make a hole to slip the antenna in. 😊 Added in October 2024. Using this antenna in northern NV at a state park for POTA, I received calls from VA and MD, KY, TN, and Canada. The BIG surprise was a call from Sweden! And of course, I had to drill a hole in the rock hard ground to set the antenna up. I LOVE this antenna and its simplicity.
I bought this antenna and tested it today out on the Salisbury Plains; managed to have a QSO with a station out in Dnipro Ukraine on FT8 20m at 5 watts on my Xeigu 6100 Really impressed with this antenna. So easy to setup you can’t really get it wrong.
2:36 i defiantly want more Radios lol.. Great video once again. I love the look of this and i have something similar home made, A huge telescopic moonraker whip and a ground spike with a tape measure attached for a adjustable ground plane and it works amazing.
Hi Mat, I have a JNC Radio MC-750 it's the same as yours, I've had it for just over a year and I like it, also have the 80 meters loading coil but haven't tried it yet doubtful how efficient it'll be on 80 considering the overall length of the antenna, but from 40 meters and above it performs just as well as any other 17 foot telescopic whip antenna, it's the package and the easy setup which works for me and where I use this antenna normally a local park, it's not so much of an eyesore for the locals using the park.
If it's a typical VNA, you should be able to change the scale on the y-axis, to say 1 to 4, and it'll give a better visual representation of the min/max.
It looks like another good portable alternative similar to the JPC-12 only with a better system for the ground radials, and the markings on the extendable radiator would certainly make tuning to each band much easier in the field. As far as it’s 40 m performance, like any antenna that is less than a quarter wave in radiated length it will not be as effective as at least a full quarter wave wire would be. Thanks for the informative comparison video. 73 de Dan WD4DB
Do you agree with this proposition: Lacking a sizable test range and a lot of RF sensing equipment, the only convenient way to test an antenna is to compare it to an on-site reference antenna, transmitting simultaneously, and compare downrange signal strengths. In any event I really enjoy your channel, it's informative! Andy WM8Q
Reviewing and testing antennas on a video is extremely difficult. Mainly because each location will see different results. Not only location, due to earth type, height, surrounding buildings etc, but also band conditions especially when testing HF antennas. That's why I switched from doing "Phone SSB" contacts in videos to using some form of digital mode like FT8 or WSPR, so that I can see who around the world has received my signal. Two important factors for me when it comes to portable antennas is 1) How easy the tuning process is (this needs to be quick) and 2) That the antenna is NOT a dummy load. Recording the transmitted sessions with digital modes helps to see if its a dummy load. Cheers and thanks for watching my videos.
@TechMindsOfficial you've come a long way from reviewing cheap aliexpress stuff to doing quality reviews. Lol, I would like to seeb your EFHW setup after seeing the A/B switch change. 73 KD9UQE
The EF antenna I was using is 71 feet of wire connected to a CHA URT1. Pre-tuned on each tested band before the comparison. Video on it here: th-cam.com/video/p0s2rEcDiLs/w-d-xo.html
Hi Mat, Great presentation of this portable antenna. Since you only showed us 40-20 meters I tend to think that your end fed seems to pick up a little more noise as it rises the noisefloor when swithing to the end fed antenna. It was clear the end fed would be the best on 40 but I was convinced the MA-12 did a very decent job on 20 meters and again for me a little less signal but a quiet noisefloor is what I would prefer. Overal considering only 4 short radials this antenna seems to do a decent job. Rasing the antenna feed point and using 1/4 wavelenght radials elevated from the ground could even outperform the groundradials but it's less simple to set up. Cheers, Phil ON4VP
Another great video Mat. Your antenna comparisons using the waterfall are very informative. Regarding the SWR plots, I'd personally like to see them over a wider frequency range so the shape of the resonance can be seen, which says something about efficiency. 73 -- Wayne K3WM
It could be great. I have the same telescope, but I'm using an old military 70cm tripleg as base stand, because we have so dry summers, I can't put a ground spike into the ground. Or sometimes I use it on asphalt, so the stand is more practical for me. It is very sensitive to the length of radials.
If you want to raise a GP antenna and not have the radials on the ground, you will likely find it difficult to get a match unless the radials are resonant. If you do use resonant radials you should get more gain than ground mounted.
I would have bought it much easier than my last that is in my holiday house in DU2.whith two coils and two wipes not marked and some pins to clip on .do you want to swap haa.
@@TechMindsOfficial10 has been incredible the last 3 days, especially the UK has had exceptional Asia and NA propo! Get your radio up and going. We haven't had 10 open like this for 6 months.
10 must of opened just after I recorded the video then. Shame as I really like 10M. I have a HEX Beam to do a build video on soon, lets hope 10 is open for then! :-)
And there I was thinking it was just me that found FT-8 like watching paint dry.👍 Thanks for the smiles and another great video. Cheers & 73 🍺

Nifty antenna, ideal plug-n-go job and not badly priced.
Does look similar to jpc-12, but non adjustable coil. Nice design for radial attachment, no need for separate ground plate. Thank you for your review!
The company that makes the JPC-12 also makes the MC-750 which is literally the same antenna as shown in this video.

I've seen a few videos with what they call a magic carpet laid out, might be better with this.
In your opinion, how did it compare to the PT- GP1 that you reviewed a while back?
It's been a long time since I have seen so much purple on FT8.
Looks like a clone of or very similar to an mc-750 that I saw in another review the other day.
O yes just about the same 😮
In fact the mc-750 is the same antenna under a different brand
JNC gets them rebranded from this factory
Ok cheers. How do you know that? Not doubting but just wondering. If so the cheaper one is good value but hoping one isn’t a rip off of the other.
@@TechMindsOfficialcheers
Soubded pretty good from 20m and above dont think id be holding my breath on 40m, that EFHW is what 20 to 30dB more favourable 😊
Lower noise floor on the vertical on 20m.
I would love to see it mounted on a mag mount on a car to see if it works (for static mobile only of course !).
Se podría hacer un gran video, de esta antena y la PAC-12
So, where is the video about your EF Antenna? ;-)
CHA URT1 video
Will this work on a rooftop??

good portable antenna...hopefully those band markers wount dissapear after a few usages
I've used my MC-750 over a dozen times and the markings are still good. I think they're etched, not printed.

Yeah, even the carrying case - with different lettering.
@@MrTommy001the only difference I can see is that the ground spike section is red instead of black. Everything else is exactly the same
Bummer! I was looking forward to seeing the results for the 10 meter band. 😢
10 was dead at the time of recording. I do have some radios to test soon, so I might feature this antenna again, and if 10 is open, I’ll test it :)

You can do 10 meters on one watt all over the world right now, it’s amazing on my G90! 🤙🏻
I have the MC-750 and in my experience 10 meters works great with it (the antenna in the video is a clone of the mc-750)
Could you weight the antenna ? For portable use, it's critical. I can read 1.8kg on the websites. If it's real, well, what an anchor.
