ECOXGEAR ATRDM660ST-2PK Medium Duty Radome UHF Antenna Twin Whip Pack – Stealth Matte

The ECOXGEAR ATRDM660ST-2PK pairs the medium-duty ATRDM660ST stealth matte radome antenna with a second, shorter 2.3dBi whip, so one antenna covers both kinds of country. Fit the 880mm 6.6dBi whip (994mm overall) for long reach across flat, open terrain, and swap to the 500mm 2.3dBi whip (613mm overall) when the track turns hilly or mountainous and a rounder radiation pattern holds the signal better. The interchangeable medium barrel-style stainless steel spring, aluminium ferrule, 4.5m TPE-jacketed low-loss coax and pre-terminated FME connector with PL259 adapter are the same as the single ATRDM660ST – a slimmer alternative to the heavy-duty ATRD pack – and both whips carry the low-glare stealth matte finish.

Suits: ECOXGEAR ECOXTALK EXG1000 and EXG3000 fixed-mount UHF CB radios (PL259 adapter included; radio sold separately).

Key Features

• Two whips, one antenna: the whip unscrews from the spring (Allen key included), so you can change gain to suit the terrain instead of carrying a second antenna
• 6.6dBi gain for open country: higher gain with a longer, flatter radiation pattern for extra reach across flat, open terrain
• 2.3dBi gain for hilly terrain: lower gain with a rounder radiation pattern, so the signal holds up on undulating, hilly and mountainous off-road tracks
• Medium-duty radome construction: fibreglass radome whip with an aluminium ferrule protects the antenna element from scrub, stone strikes and weather, in a slimmer package than the heavy-duty ATRD series
• Interchangeable medium barrel spring: matte-coated stainless steel spring, Ø45mm at its widest, absorbs knocks and lets the whip flex through scrub
• Stealth matte finish: low sheen for diffused reflectivity under night lighting, so there is less glare from headlights and campsite lights
• 4.5m low-loss coax cable: TPE jacket for flexibility, UV resistance and abrasion protection on the run through the engine bay or A-pillar
• Pre-terminated FME female connector with PL259 adapter: connects to a fixed-mount UHF CB radio without cutting or crimping the cable
• 30mm mount thread: longer thread for a more secure fit in most bull bar and bonnet mounting brackets
• UHF CB 477MHz, ground-independent design: does not rely on the vehicle body as a ground plane, so mounting position is flexible
