CB Antenna

CB Antennas

• Can I cut the coax on my CB antenna? Generally NO! On most Shakespeare CB antennas the coax is part of an electronically "tuned" system, and should NOT be cut or altered. Shakespeare only has two CB antennas on which it's okay to trim the coax: Styles 5223 and 5207. Note that this applies to CB antennas - VHF antenna coax is not part of a tuned system, and can be trimmed.
   
• Can I take the PL-259 connector off to feed the coax through a hole? No, this will change the tuning of the antenna - and also voids the warranty.  If coax needs to be passed through a bulkhead, be sure to add additional coax which can be cut or altered.
   
• Can I tune the antenna? Most Shakespeare antennas are pretuned at the factory and do not need any additional tuning. Shakespeare Styles 5223 and the 5207 can be retuned after the coax has been cut. Instructions for doing so are packed with the antennas.
   
• Why does my antenna system have a high SWR? There can be quite a number of reasons for this. The most usual reasons are coax having been cut or altered, coax running through conduit, antennas located near metal objects, or people standing too close to the antenna while SWR readings are being taken.
   
• Do I need a ground plane for my CB antenna? No, all Shakespeare Marine CB antennas have independent ground planes built into them.
   
• Which way should the radials for the Style 318-GBT Pogo Stick point? The radials can point either up or down. Neither direction will affect the performance of the antenna.
   
• Do I need to cut the coax in wavelengths? No. Shakespeare's CB antennas do not require this type of tuning.
   
• Can I add coax to the antenna? Yes. Shakespeare suggests that if adding more than 25 feet, use RG-8X or RG-213 (RG-8U) coax
