JPC-12 HF Antenna for Ham Radio, 7MHz-50MHz All Band Vertical Antenna with Sl
The portable HF antenna weighs approximately 3.09 pounds. The backpack length of the HF antenna is 13.58 inches. The total length after installing the HF antenna is 16.142 inches. Frequency: It can operate in 8 bands of 1574.8, 1181.1, 787.4, 669.29, 590.55, 472.44, 393.7, and 236.22 inches (7MHZ-50MHz). One aluminum alloy base (anodized to black) 2. Multi-band additive coil (material: nylon, Note: Adding coil for mold opening and making non-manufacturing) 3. One ground anchor, size 0.39× 9.44 inches (not plated to maintain good grounding) 4. Alumina tubes 4 (black), size 0.74 × 12.59 inches (anode sandblasting oxidation) 5. Top 98.42 inches stainless steel rod antenna 1 (customized thickened) 6.
One network of 10 strands of ground wire (use it as needed to tear open, generally tear 3 strands) 7. 1:The portable HF antenna weighs approximately 3.09 pounds.
The backpack length of the HF antenna is 13.58 in. The total length after installing the HF antenna is 13.45 ft. Portable high-frequency antennas can be easily installed by one person within 3 minutes. Its user-friendly split design makes it easy to carry and compact to store. Very suitable for outdoor platforms, business trips, or balcony installations.
2: Frequency: It can operate in 8 bands of 131.23 ft(40m), 98.42 ft(30m), 65.61 ft(20m), 55.77 ft(17m), 49.21 ft(15m), 39.37 ft(12m), 32.8 ft(10m), and 19.68 ft(6m) (7MHZ-50MHz). Maximum power of SSB: 100W. The SWR of the 131.23 ft(40m) band is less than 1.3, while the SWR of other bands can be adjusted to 1.1, allowing for stable low standing wave ratio (SWR).Obtain Reference Data for Specific Frequencies:? 7MHz: Wrap 4 coils near the side of the aluminum tube, retract the pull rod approximately 3.93 in (10 cm), SWR: 1.1-1.3 (on the red line marked with silver). 14MHz: Wrap 6 coils near the rod antenna side, retract the pull rod about 7.87 in (20 cm), SWR: 1.1-1.3 (on the red line marked with gold). 21.4MHz: Use 4 sections of the aluminum tube plus 7 sections of the rod antenna, extend by 3.93 in (10 cm), SWR: 1.1-1.3. 29.6MHz: Use only the rod antenna, fully extend it and then retract by about half a section, SWR: 1.2.
Note: Ensure the shrapnel contacts only the marked coils and avoid touching adjacent coils. 4: When using a dedicated grounding network, simply tear off 3-4 pieces. Adjusting the angle of the grounding grid can change the impedance of the antenna. Performance:The JPC-12 amateur radio high-frequency antenna delivers exceptional signal reception and transmission, thanks to its low standing wave ratio (SWR) and highly efficient design.
Specifically engineered for transmitting and receiving HF and VHF radio signals, it is fully compatible with all amateur radio transceivers. Its optimized design ensures enhanced signal performance without requiring an analyzer or tuner. 6:Package Contents:4 Aluminum Tubes, 1Aluminum Alloy Base, 1Multi-band Inductive Coil, 1Stainless Steel Rod Antenna(Pulled length: 98.4 in), 1Ground Anchor, 1Ground Mesh(10 Strands).
