STINGER KIT (PERMANENT) · Compact Artificial Ground / RF Return
A compact elevated counterpoise or ground-plane system for tuned vertical antennas when full-length wire radials cannot be deployed safely.
Six short stainless elements instead of long ground wires
Build a controlled RF return inside a restricted footprint
The CHA STINGER KIT (PERMANENT) is an electrical RF-return system—not a mast, clamp, stake, or stand. Six 48-inch stainless-steel elements screw into the supplied CHA HAT HUB to form a compact counterpoise or ground plane.
Use it with a source-governed tuned vertical such as a CHA MCC 2.0 / CHA PRV 2.0 component stack when wire radials would obstruct a balcony, parking area, small boat, table, walkway, or another occupied site.
Quick product reference
What the complete kit contains
- Primary RF role
- Compact artificial ground / counterpoise for a governed vertical antenna
- Elements
- Six 48 in stainless-steel elements with teardrop ends
- Hub
- One CHA HAT HUB with six element positions
- Fasteners
- Six stainless-steel 8-32 × 1/4 in set screws
- Central interface
- 3/8-24; the completed antenna stack and support path must be source-governed
- Deployment count
- Use up to all six elements as required by SWR, clearance, and the approved mounting arrangement
Where it solves the right problem
Use it when wire radials create a hazard or do not fit
- Restricted sites
- Small condo balconies, busy parking areas, occupied walkways, tables, and other locations where loose wire radials could be stepped on or become a trip hazard.
- Elevated installations
- Governed CHA UCM, CHA CARBON FIBER TRIPOD, CHA SPIKE MOUNT, CHA SURVEYOR-A, CHA PORTA-MAST / MAST TOPPER, CHA JAWMOUNT, or equivalent documented 3/8-24 support paths.
- Marine use
- A compact option on a small boat when long wire radials cannot be deployed; the complete marine mount, bonding, clearance, weather, and RF-exposure path still requires verification.
- Electrical isolation
- For a tuned vertical, place CHA SS INSULATOR between the conductive or ground-coupled support and the complete STINGER/HAT-HUB plus feed/radiator assembly.
Controlled stack
- Secure the documented mechanical support.
- Install CHA SS INSULATOR above any conductive or ground-coupled support hardware.
- Install the CHA HAT HUB and the required STINGER elements on the antenna side of the isolation boundary.
- Install the governed feed, matching/loading, and radiator stack above the RF return.
- Route a feed-point-choked coax cable, then tune and verify the completed antenna at low power.
Commercial options
The product record offers Hub Only, Stingers Only (6 pieces), and the complete Stinger Kit (Permanent). A governed Builder return path requires the complete kit, or the exact combination of one CHA HAT HUB plus six CHA STINGER elements already owned.
