What many people don't know is that the cause can not only be improper adjustment of the antenna but also bad cabling. So please check whether you have proper coax cable, it is not broken and you have the shield connected properly. If the eches come from the air, you might try to "disadjust" the antenna in a way that the echoes get reduced. Best regards Hartmut
