Hi I'm new to this and was looking for information about a replacement antenna on the WEB abd found this site. I recently purchased a motor home which has a CB/weather radio mounted in the dash. The antenna is a thru glass mounted type. There is no drilled holes which would sandwich the glass simply adhesive on both sides. The outside antenna and mount has fallen off. Don't know the brand of antenna. Question, can I simply use any replacement antenna as long as the mounts are the same size? Is there any frequency issues I need to worry about?
