Radio Antennas JPC-12 HF Antennas for Ham Radio with Slide Regulator 7MHz-50MHz All Band Hf Vertical Antenna 40m-6m 8 Bands JPC-12 Antenna for Outdoor 4.1 Meter(13.5Ft) (M10). Experience optimal performance with this Multi Band HF Antenna, capable of working in 40.30.20.17.15.12.10.6 meter 8 bands. Its frequency range spans from 7-50MHz, with an impedance of 50?
And a maximum power of SSB-100W. The sensing coil has been optimized, and an additional spring has been added to the original design, increasing the force of the spring to ensure more reliable contact with the coil. The new version of the antenna features a sliding regulator that replaces the adjusting screws and plugs found on the old model. By simply sliding the adjustment block, adjusting the standing wave becomes straightforward and effortless.
Enhance your signal and enjoy excellent reception with these portable mobile ham radio antennas. Designed for both transmitting and receiving HF and VHF radio signals, they are highly preferred by operators seeking top performance. Fully compatible with all Amateur Radio transceivers, no analyzer or tuner is required but can be beneficial. Lightweight and portable, this HF broadband antenna weighs only 1.35KG.
It can be easily set up by a single person within 5 minutes. With its user-friendly design and split structure, it is convenient to move and compactly store.
Perfect for outdoor platforms, business trips, or balcony installations. The package includes the entire antenna system for Ham Radio, which can be carried in the provided black Carry Bag.
Gain reference data for specific frequencies: 7Mhz with 4 circles near the aluminum tube side, retracting the pull rod approximately 10cm, SWR: 1.1-1.3 (on the marked red line with silver). 14Mhz with 6 circles near the rod antenna, retracting the pull rod about 20cm, SWR: 1.1-1.3 (on the marked red line with gold). 21.4Mhz with 4 sections of aluminum tube plus 7 sections of rod antenna + 10cm, SWR:1.1-1.3. 29.6Mb with rod antenna only, fully extended and retracted about half section, SWR: 1.2. Note: Ensure shrapnel contacts marked coils only, avoiding adjacent coils. Benefit from optimal signal reception and transmission with the low standing wave ratio (SWR) and efficient design of the JPC-12 antenna. Whether you're a seasoned enthusiast or a beginner, this antenna offers reliable performance and improved efficiency. The package contains Aluminum Tubes 4, Rod Antenna (Top 2.5m) 1, Ground Anchor 1, Ground Mesh 10 Strands 1, Aluminum Alloy Base 1, and Multi-band Inductive Coil 1.All components collapse down and fit into the stealth black Carry Bag zip case. The theards on the aluminum rods is M10 size. If you encounter any problems while using the product, please feel free to consult us and we will reply to you within 24 hours. 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. Tearing off 3-4 roots of ground mesh to be used. Adjusting the angle omesh can change the impedance of the antenna.
Any product you return must be in the same condition you received it and in the original packaging. We usually respond within 24 hours on weekdays. Thank you for shopping at our store.
