Ground independent for flexible mounting locations. Pre-fitted with 4.8 metres of RG58 coaxial cable terminated with a female FME connector, plus an FME to PL259 adaptor and mounting nut for a complete ready-to-install solution.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cstrong\u003eProduct overview\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThe CBA31 is built for situations where antenna height or profile is a constraint. At 380mm total length it is one of the most compact UHF CB antennas available, suited to vehicles with height restrictions such as carport clearances, low-hanging branches on bush tracks, and installations where a tall antenna would foul surroundings or draw unwanted attention.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe 3.0dBi gain produces a broad, wide-angle radiation pattern rather than concentrating gain along the horizon. This broad pattern performs well in hilly, mountainous, and undulating terrain where elevation changes are frequent and signals need to reach in multiple directions rather than at a fixed elevation angle. The trade-off relative to higher-gain antennas is reduced flat-horizon range, but for off-road use and varied terrain the wide coverage is more practical.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe ground-independent design allows flexible mounting locations without compromising performance. The integrated spring absorbs vibration from corrugated roads and off-road terrain, protecting the mast and base. The weather-sealed construction handles dust, rain, and the environmental exposure typical of tough 4WD and rural use.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cstrong\u003eFeatures and benefits\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003e3.0dBi broad radiation pattern - suited to hilly and undulating terrain:\u003c\/strong\u003e Wide-angle coverage in multiple directions rather than concentrated gain along the horizon, performing well in mountainous, hilly, and off-road environments with frequent elevation changes.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eUltra-compact 380mm total length - suited to height-restricted vehicles:\u003c\/strong\u003e One of the most compact UHF CB antennas available, suited to low-clearance situations and discreet, low-profile installations.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eGround independent design:\u003c\/strong\u003e Allows flexible mounting without degrading antenna performance, unlike antennas that rely on a vehicle metal ground plane.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eIntegrated spring for vibration resistance:\u003c\/strong\u003e Absorbs vibration from corrugated tracks and off-road terrain to protect the mast and base.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWeather-sealed plastic tube whip construction:\u003c\/strong\u003e Built for dust, rain, and the environmental exposure of tough 4WD and rural use.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003e4.8 metre RG58 FME pre-terminated cable included:\u003c\/strong\u003e Pre-fitted cable with sufficient length for routing from antenna to radio in most vehicle layouts.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFME to PL259 adaptor and mounting nut included:\u003c\/strong\u003e Allows direct connection to UHF CB radios using the standard PL259 antenna socket.

A 3.0dBi antenna spreads its pattern more broadly, which is more effective in hilly, mountainous, and undulating terrain where vehicles and other radios are frequently at different elevations. For remote outback flat-terrain use where maximum horizon range is the priority, a higher-gain antenna may be more appropriate.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhat does ground independent mean for this antenna?\u003c\/strong\u003e A ground-independent antenna does not require a metal ground plane beneath the base to operate correctly, unlike rooftop and magnetic mount antennas that rely on the vehicle body. The CBA31 maintains consistent performance regardless of where it is mounted on the vehicle.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhat is the integrated spring for?\u003c\/strong\u003e The integrated spring absorbs vibration and flex from corrugated roads and off-road terrain, reducing stress on the antenna mast and base connection. This protects the antenna from fatigue damage during extended use on rough tracks.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhat connector does the cable use and what is the PL259 adaptor for?\u003c\/strong\u003e The 4.8-metre RG58 cable is pre-terminated with a female FME connector. The included FME to PL259 adaptor allows connection to UHF CB radios fitted with the standard PL259 (SO-239) antenna socket, covering the majority of fixed mount UHF CB radios.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eDoes the 380mm length include the spring and base?\u003c\/strong\u003e Yes. The 380mm total length covers the complete antenna assembly. The mast itself measures 335mm with a 10mm width. The mounting thread is 10mm for fitting to compatible brackets and mounts.\u003c\/p\u003e","brand":"Aerpro","offers":[{"title":"Default Title","offer_id":44917490843741,"sku":"CBA31","price":39.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/9528\/9437\/files\/CBA31_600.jpg?v=1787197281","url":"https:\/\/frankiesautoelectrics.com.au\/products\/aerpro-cba31-3dbi-compact-uhf-cb-antenna-477mhz-380mm-black","provider":"Frankies Auto Electrics","version":"1.0","type":"link"}
