Home Patrol on its way

I live in Indiana, I am told the Home Patrol is really the only game in town.



Last night I finally caught one on Amazon refurbished for a price I would pay.



So its suppose to be on its way! Should be here next week.



I am pretty rural, but most of the listening we are interested in would be in a 20 mile radius.

Will I need an out door antenna? We are in hilly southern Indiana.



If I need an outdoor antenna; what and where to get it?



Thanks
