This is an Ultra-wideband Log Spiral Antenna with a main frequency range of 400MHz to 3GHz and beyond. The antenna is low-gain(omni-directional) circularly polarised. It is provided with an SMA connector and suction mounts for attachment to RF transparent surfaces such as glass.

NEW IMPROVED This is an improved version of my older 300MHz and 800MHz designs. Enhancements include...

• High Quality Genuine Rosenberger SMA connector. More robust Mid Mount design. Better Return Loss.
• Greatly Improved Suction Mounts. For more secure mounting.
• Grab Handles. For improved...Grabbing
• Cable Strain Relief.
• Improved Feed Design.
• Frequency extension connections. Tip! Add some wire extensions to improve low freq performance.

Dimensions :- 260mm x 210mm (10.2" x 8.3").

Performance VSWR <2:1 400MHz to 8GHz

The antenna provides Left-Hand Circular Polarization in one broadside direction and Right-Hand Circular Polarization in the opposite direction. Marking is provided on each side of the antenna to show the direction of polarizations radiated in that direction.

This antenna is suitable for a wide range of applications. The supplied suction mounts make it great for a mobile setup. Great for car, office, hotel window.
