Sirio Twin-Log 3 CB Mobile Antenna 26.6-27.9MHz, 900W Peak, 95cm, 3/8"

The Sirio Twin-Log 3 is a compact high-power CB mobile antenna using Sirio's parallel twin-wire logarithmic loading system to reduce RF resistance and heat loss. It is tunable across 26.6-27.9MHz and uses a heavy-duty fibreglass radiator with a standard 3/8"-24 male thread.

At approximately 945mm tall, the Twin-Log 3 offers a practical balance between size, bandwidth and power handling for mobile CB installations.
