LINK-D15 · Accessories & Components
A replacement, service, interface, or modular accessory for a documented product or system.
Why operators make room for it
CHA LINK-D15: add the radiator or return path the documented system calls for
The smallest missing interface, replacement part, or service component can stop an otherwise complete field station at the tailgate. The CHA LINK-D15 is a high-performance linked dipole antenna extension designed exclusively for use with the CHA LEFS 4010 system. Engineered for rapid deployment and multiband operation, the LINK-D15 allows amateur radio operators to seamlessly operate on the 40 meter , 20 meter , and 15 meter HF bands without requiring an antenna tuner. The operator gets a specific way to complete, adapt, or maintain the intended product without confusing physical fit with full RF, power, environmental, or structural compatibility.

CHA LINK-D15 (Linked Dipole)
Multi-Band Resonant Dipole Add-On for CHA LEFS 4010
Covers 40M, 20M, and 15M Bands — No Antenna Tuner Required
The CHA LINK-D15 is a high-performance linked dipole antenna extension designed exclusively for use with the CHA LEFS 4010 system. Engineered for rapid deployment and multiband operation, the LINK-D15 allows amateur radio operators to seamlessly operate on the 40 meter, 20 meter, and 15 meter HF bands without requiring an antenna tuner.
Built for field communication, portable deployment, and emergency response, this antenna extension offers exceptional reliability, fast configuration, and a rugged design that meets the demands of both professional and recreational operators.
Multiband Performance Without a Tuner
The CHA LINK-D15 uses precision-measured wire segments and preinstalled band links to enable optimized operation across three popular HF bands. With no need for tuning or additional equipment, operators can quickly switch bands by adjusting the integrated alligator clip jumpers, giving them the flexibility they need in real-time scenarios such as POTA activations, SOTA excursions, EMCOMM field stations, or backcountry communication.
Flexible Installation Options
The antenna can be installed in a horizontal or inverted-V dipole configuration, depending on available space and operating goals. Sturdy carabiners and strain relief holes provide solid wire support, while terminal lugs ensure reliable, corrosion-resistant electrical connections at each segment.
The center feed point is fitted with a BNC connector, making it compatible with a wide range of portable and stationary transceivers and feedlines.
Simple Band Switching
Operators can change bands by setting or removing the supplied link jumpers. The configuration chart is as follows:
| Band | 15 to 20 Meter Link | 20 to 40 Meter Link |
|---|---|---|
| 15 Meters | Open | Open |
| 20 Meters | Connected | Open |
| 40 Meters | Connected | Connected |
This setup ensures rapid reconfiguration in the field with minimal interruption, eliminating the need for SWR adjustments or antenna retuning.
