VR-125D | Compact 25W VHF Cavity Duplexer
The perfect space-saving solution for mini repeaters and portable VHF go-boxes. Decoded for pros: 1 (136-174MHz) | 25 (25W Power Rating) | D (Duplexer).
Mini Form-Factor.
Full-Size Isolation.
Don't let the compact size fool you. Designed specifically for lower-power nodes and portable field communication setups, the VR-125D utilizes scaled high-Q internal VHF cavities to maintain an exceptional ≥80dB isolation. It successfully prevents receiver desensitization, ensuring clear signals in a fraction of the desktop space.
Perfect Companion For:
Portable Emergency Go-Boxes, VHF Amateur Repeater Nodes, Backpack Repeaters, and Low-Power VHF Hotspots.
Why the VR-125D Excels
Space-Saving Footprint
Significantly smaller and lighter than standard 50W base station variants. It drops right into tight field-enclosures, portable glove boxes, or tactical packs without weighing down your off-grid setup.
Optimized Insertion Loss
Maintains an ultra-clean transmission line with minimum power attenuation (≤1.2 dB). Almost the entirety of your 25W radio output goes cleanly up to the VHF antenna mast.
Stable Resonator Design
Built using durable, temperature-compensated tuning layouts to prevent frequency drifting from -25 degrees Celsius up to +55 degrees Celsius, maintaining precise tune parameters over long duty cycles.
