Description
Midland PRO70 - 6.9dBi Elevated Feed UHF Antenna 954mm with LMR240 Cable
Product Overview
The Midland PRO70 is a high-performance 6.9dBi elevated feed UHF antenna engineered for serious 4x4 enthusiasts, recreational tourers, and commercial fleet operators demanding superior communication range. This professional-grade antenna features 954mm heavy-duty 8mm fiberglass whip with elevated feed design and 45mm heavy-duty barrel spring, delivering exceptional signal gain and durability for demanding Australian conditions. The PRO70 includes 4.5 meters of professional-grade LMR240 low-loss coaxial cable with FME female connector, providing superior performance compared to standard RG58 cable through reduced signal resistance. Pre-tuned for 477MHz Australian UHF CB frequency with ground-independent design, this antenna installs on any vehicle surface without requiring metal ground plane. The 15-degree vertical beamwidth and 200-watt power handling capability make the PRO70 ideal for extended-range communication across remote outback locations, mining operations, agricultural properties, and commercial applications requiring reliable long-distance UHF connectivity.
Key Features
High-Gain 6.9dBi Performance - Advanced 6.9dBi gain delivers exceptional communication range extending well beyond standard antennas, enabling reliable contact across greater distances in remote outback locations, mining sites, and agricultural operations requiring maximum coverage.
Elevated Feed Design - Specialized elevated feed configuration optimizes radiation pattern for improved signal efficiency and reduced ground losses, providing enhanced performance compared to standard antenna designs for superior transmission and reception capability.
Professional-Grade LMR240 Cable - 4.5-meter LMR240 low-loss coaxial cable significantly reduces signal resistance compared to standard RG58 cable, maximizing power transfer from radio to antenna while minimizing signal degradation for superior communication performance.
Heavy-Duty 8mm Fiberglass Whip - Robust 8mm fiberglass whip construction provides exceptional durability and flexibility, withstanding branch impacts, extreme weather conditions, and harsh Australian outback exposure while maintaining optimal signal transmission characteristics.
45mm Heavy-Duty Barrel Spring - Robust 45mm diameter barrel spring absorbs impacts and vibration from rough terrain, corrugated roads, and demanding off-road conditions, preventing antenna damage during 4x4 adventures and commercial operations.
Ground Independent Design - No ground plane requirement enables installation on fiberglass canopies, aluminum trays, composite body panels, or any vehicle surface without performance degradation, providing flexible mounting options for modern vehicles.
Pre-Tuned 477MHz - Factory-tuned for Australian UHF CB frequency band eliminates complex antenna tuning procedures, ensuring optimal performance across all 80 UHF CB channels immediately upon installation without additional adjustments.
15° Vertical Beamwidth - Narrow 15-degree vertical beamwidth concentrates signal energy toward horizon for maximum long-distance communication range, ideal for flat terrain, highways, and remote locations requiring extended reach.

Installation Notes
The Midland PRO70 installs on any UHF antenna base or bracket with standard thread mounting. Thread the antenna with spring assembly onto the mounting base, tightening firmly by hand without over-torquing the barrel spring connection. Route the 4.5-meter LMR240 cable to the radio location, avoiding sharp bends that could damage the cable. Connect the FME female connector directly to compatible radios, or use the included FME to PL259 adaptor for standard PL259 radio connections. The ground-independent design allows mounting on non-metallic surfaces without performance loss. Ensure the antenna remains clear of overhead obstacles and other antennas to prevent interference. Test VSWR after installation to verify proper connection and tuning. The heavy-duty barrel spring absorbs impacts during off-road driving while maintaining vertical antenna orientation for optimal signal propagation. The 954mm height provides excellent range while fitting most vehicle height restrictions.
Frequently Asked Questions
What is elevated feed design and how does it improve performance?
Elevated feed design positions the antenna's feed point higher on the whip element, optimizing the radiation pattern for reduced ground losses and improved signal efficiency. This configuration provides better performance compared to base-fed antennas, particularly in ground-independent installations, delivering stronger signals and extended communication range.
How does the PRO70 compare to the PRO6000 antenna?
The PRO70 offers slightly higher 6.9dBi gain versus PRO6000's 6.6dBi, with shorter 954mm height versus 1.026m. The PRO70 uses elevated feed design with 8mm fiberglass whip while PRO6000 uses 20mm radome mast. Both include LMR240 cable and provide excellent performance, with PRO70 offering marginally better gain in slightly more compact package.
Is the 954mm height suitable for parking garages?
The PRO70's 954mm height is approximately 72mm shorter than the PRO6000, providing better clearance for restricted-height situations. When mounted on typical 4x4 roof racks or bullbars, verify total vehicle height remains within parking garage limits. The shorter height makes PRO70 more suitable for vehicles requiring occasional urban parking access.
Can I install this antenna on a fiberglass canopy?
Yes, the PRO70 features ground-independent design requiring no metal ground plane beneath the antenna. This enables installation on fiberglass canopies, aluminum trays, composite tonneau covers, or any vehicle surface without performance degradation. The elevated feed design particularly benefits ground-independent installations by optimizing radiation pattern efficiency.
What is the advantage of LMR240 cable?
LMR240 professional-grade coaxial cable provides significantly lower signal loss compared to standard RG58 cable used in most antennas. The reduced resistance means more transmit power reaches the antenna and weaker received signals maintain better quality, directly translating to extended communication range and improved clarity across all UHF CB channels.
