The item most overlooked when ordering a custom radio is the microphone.  Your new tuned radio will NOT
sound great  with a stock mic on it  If your CB is more than a tool for work, you NEED to upgrade your microphone. 
My personal favorites are the Astatic 636L and RD104E.

If you place an order from outside the continental USA, we will calculate your actual shipping and send you a PayPal payment request.  We do NOT export Antennas or Base station radios.

Orders requiring technical work are shipped
 in about 3 to 14 days.

Heads up- The Price of many China-made
 items went up due to tariffs.
