Price: $49.99

The K40 Trucker CB Antenna is perfect for semis and the professional CB Radio user. Because the RF signal travels on the surface of the wire, the larger the surface area (skin effect), the lower the resistance. The lower the resistance, the higher the efficiency of the antenna. Higher efficiency means less RF signal loss and more gain. Simply put, you talk further and receive clearer!

General Return Guidelines

Products must be in its original unused condition to be considered for return (please see below for manufacturer defects, damaged goods, or missing items). All customers must return the item within 30 days of your purchase. Returned items without a Return Merchandise Authorization (RMA) will not be accepted.  Buyer is responsible for any return freight or shipping costs plus a 15% restocking fee. 

Buyer is responsible to notify seller of any shortage or damaged products within 3 working days of receipt. The buyer is responsible for performing the following:

  1. Inspect shipment for lost or damaged items.
  2. Sign freight bill as “short”, “damaged”, or “subject to further inspection”.
  3. Obtain signature of carrier acknowledging lost or damaged merchandise.
  4. Notify Freight Company of claim and request inspector. Seller is unable to handle damage claim for you, since all damage claims must be adjusted at the delivery point per ICC regulations.

Failure to inspect goods within 3 working days of receipt of goods by the buyer constitutes a waiver of buyer’s rights to inspect and constitutes acceptance of goods in current condition. Costs of inspections are buyer’s responsibility. Requests for RMA’s for shortage or damaged goods after the initial 3 working days are subject to a higher restocking fee, not to exceed 40% at anytime.
