The radials provide the ground plane reference needed for correct antenna operation and optimal SWR, making this the preferred version for most mast-mounted base station setups.\u003c\/p\u003e\n\u003cp\u003eCovers \u003cstrong\u003e26–28 MHz\u003c\/strong\u003e with a gain of \u003cstrong\u003e4.2 dBi\u003c\/strong\u003e and maximum power handling of \u003cstrong\u003e1,000 Watts\u003c\/strong\u003e. The 5\/8λ wave design provides a lower radiation angle than a quarter-wave antenna, directing more signal towards the horizon for improved ground-wave CB range. SWR 1:1.3 at resonance.
