the date the antenna is returned (at purchasers expense) to Cushcraft or one of its authorized representatives.  This warranty is in lieu of
all other expressed warranties, any implied warranty is limited in duration to one year.  Cushcraft  Corporation shall not be liable for any
incidental or consequential damages which may result from a defect.  Some states do not allow limitations on how long an implied warranty
