Product Description
Good Build Quality
It is compact and lightweight, making it ideal for hiking, camping, or other outdoor activities. With the ability to tune to a wide range of frequencies, this antenna is perfect for the ham radio operator on-the-go. The JPC-12 is a durable and reliable antenna that is designed to last for many years of use.
Easy to Assemble
1. Put the connecting ring of the ground mesh directly on the screw of the ground anchor and screw it to the base, and then comes the connecting seat-four-aluminum tube -the induction coil- the rod antenna
2. Adjusting the SWR, when there is an antenna analyzer, first to find the lowest point of the standing wave to see the resonant frequency is high or low. If the resonant frequency is high, it means the antenna is too short, then to lengthen the rod antenna or increase the number of induction coin loops. If the resonant frequency is low, then to shorten the rod antenna or reduce the number of induction coin loops
If there is no antenna analyzer, use the standing wave meter of the radio station, set it in FM, AM or RTTY mode, reduce the transmit power to about 10 watts, press the transmit button, adjust the radio frequency knob, and search for each frequency band
the minimum point of standing wave, look at the level of resonance frequency, and then use the above method to adjust.
3. Tearing off 3-4 roots of ground mesh to be used. Adjusting the angle mesh can change the impedance of the antenna.
- It is made with lightweight, high-quality materials, and can be set up easily for use in any location. Whether you're out hiking, camping, or traveling, balcony, the JPC-12 Antenna is the perfect antenna to take with you. (be sure to pay attention Safety, take protective measures, the user shall be responsible for the personal injury or financial loss caused by the fall, and the seller shall not bear any responsibility)
- With the ability to tune between 7 and 50 MHz, this antenna can handle a variety of frequencies.
- The reference data of sliding regulator:
- 7MHz in 4 circles near the side of the aluminum tube, the pull rod retracts about 10cm, SWR 1.1-1.3 (on the red line marked with silver)
- 14MHz in 6 circles on the side close to the rob antenna, the pull rod retracts about 20cm, (on the red line marked with gold) SWR 1.1-1.3
- 21.4MHz with 4 sections of aluminum tube plus rod antenna 7 sections +10cm, SWR1.1-1.3
- 29.6Mb with rod antenna only, pull out all and retract about half section, SWR 1.2
- NOTE: Shrapnel contacts only contact the marked coil, do not contact the adjacent coil
- The above parameters may vary slightly depending on the environment, and can be fine-tuned according to your actual situation.
Antenna Installation Showcase
- The antenna can be installed both horizontally and vertically
- For horizontal installation, it can be mounted on a balcony with the ground mesh laid out or hanging down
- For vertical installation, it can be stuck into grass or sand

Surprisingly good antenna. Easy to deploy and works great 40-10. Better if you have a tuner.

The only reason I ding this product one star is the documentation. It is severely lacking, and wrong. There is a cheat sheet available on the internet, use it!I connect to a cheap USDx HF QRP TRANSCEIVER (aka Chinese black brick) via RG8x coax. Holy smokes! Unbelievable!From Houston I've made voice contacts with Florida, Wisconsin, California, Montreal (Canada) and last night my first DX to Panama! On 4 watts! Yes, FOUR watts QRP!Needless to say, this antenna rocks! Tear the ribbon in groups of two so you'll have 5 radials. Setup is quick (5 minutes for this slow guy). Breakdown is the same. When removing from the ground, DO NOT pull with the aluminum pieces. Take those off first and ONLY pull from the rough edge of the base. See YouTube.The case fits in my backpack nicely and the antenna does well in the wind. Performance is fantastic.Ignore the directions. For 20 meters, I get over 2.3 SWR using the gold & red coil marker. But exactly 1 coil down, I get a real nice 1.01. When I use 40 meters, I click up 4 coils above the recommended silver & red coil for a 1.3 SWR reading.I so badly want to give this thing 5 stars. But man... They have got to do something about the documentation.That being said I HIGHLY recommend this antenna and I WILL buy another one when the time comes!

Used primarily for the 20-meter and 40-meter band, I found it easy to tune with a manual tuner and got some excellent reception several states away (in the middle of the summer during the day). It was very easy to set up- and easy to pack up. Great for portable work!

This is a great portable antenna that I use with my Xiego X6200. It is very easy to use and setup. For optimum performance, please read the instructions. You can setup the antenna in about 3 minutes. I have gotten the SWR down to 1.1 on several bands with 3 ground radials about 10m long with small length adjustments right out of the box. I've been using a small (1m dia) mag loop antenna and it's an excellent antenna but it's not very easy to carry and include on backpacking trips for SOTA activities. The JPC-12 is !! It comes with a very nice carrying case (about the size of a small laptop case) and is quick to set up. I like the selectable coil for different bands and I've experimented moving the coil to the bottom without the extension rods and using only the whip antenna for the CB bands, it works great ! Just be careful with the whip antenna and pull the sections out with care, I've seen too may people jerk the whip apart on other model antennas. A friend of mine bought the JPC-12 and he highly recommended it, I'm glad I did !I would highly recommend this antenna for the newbie (like me) as well as the experienced ham operator. The price and build quality is great !

You will need to go to the internet for better instructions. There is a set of guides from people that experimented with the positioning of the coil.The radials make poor contact with the ring connector, that will need to be fixed. Don’t split the radiant to individual wires, 2 wires at the min.Maybe make better ones with better wire.Antenna performance was very good, for the price it worked really well.

This is my first attempt at HF so I wanted something that wouldn’t break the bank, something I didn’t have to figure out how to build (yet), and something that could work multiple bands. This is a great choice for all of those things and more. The build quality is solid, the price point isn’t terrible in my opinion, and signal strength has been great. As a Tech I’m only using it on 10m phone right now but I’m studying for my General as we speak and look forward to jumping into the other bands with this antenna. I live in an HOA in Texas and I can hide the antenna behind a smaller tree in our yard. I haven’t noticed no problem reaching contacts as far as Argentina using less than 100W.If you’re thinking about picking one of these up I would definitely recommend it.

I wanted an antenna for HF that was basic, easy to carry and set up. But it ale had to perform. I set this up the first time, and pre set the coil for 20 Meters, and added four radials. My SWR came out to 1.06! I was very impressed. My radio is a basic Yeasu 450D and with it set to 25 watts, I was able to make several contacts across the US. The propigation was not well at all, but I was able to make clear 2 way with them. BTW, my noise level was very low (3 or so) No noise. This allows me to receive weaker stations and is very helpful.I can carry this antenna very easy with the included case. It takes just a couple minutes to set up. One important feature is the coil, which sometimes needs to be adjusted, is mid way up the antenna and that is a dream to adjust standing up. No more getting on your knees to see it. Really a great design feature. I am very happy with this product. Its great for POTA and ARES during hurricane season. It is now a major part of my portable kit. N4JEP

I'm sure the antenna is great except as soon as I went to extend the telescopic antenna, it literally fell apart before I could even extend it. It seems like the little tabs that hold the telescopic sections from coming apart were missing in at least one or two sections.This is a little concerning from a quality control standpoint.*UPDATE*Seller promptly issued a refund and exchange, seems like this was a crimping error in the telescopic section. All other components are great.

This antenna sets up easily, low SWR, and gets out. I've been using it to activate Parks very successfully and love the quick setup and quick tear down and portability.
