If you do this, you have 2 good sets: One as a hide-able mobile in your rig and one to loan or use as a walkaround handheld.
Get an amateur radio operator license as it’s illegal (except in true emergency) to use those Baofeng ht’s to transmit without a license. The technician license is quick, easy, n cheap. Study here (http://www.hamradiolicenseexam.com/?gclid=CKeXoImix68CFcIDtgodI0-dYA) n get the tech and general in one sitting. You can even get the Extra if you want. Google (your city) amateur radio n get to know the local ham community. They’ll administer your exam n teach you/help you learn and study. Ask them for an Elmer, it’s a ham radio mentor.
Anyway, with this idea, you can pop this antenna setup on/off for going through car wash or hiding it if in a questionable environment. If you’re in a wooded area, you can easily swap for either shorter, or longer, antennae depending on terrain n distance needed to communicate. Yes, some will argue wattage but I’ve never had a problem where more watts is better than more antenna. I live in the Southwest desert region with quite a bit of mountains and i do just fine with lower wattage as long as my antennae rock it right. So far, I find it to be useful to have a short n a long magmount antenna set up for my 2m/70cm ham and another one for cb for these reasons.
Here’s a pic of my old setup on my Big Blue Box, it’s a midland 75-822 w/speaker mic and a kenwood thf6a ham w/speaker mic. My 2 yellow Baofeng uv-5r are in that bag... The antennae are the short ham 2m/70cm and a firestick II on magnetic mounts. I get all over my local area and hit all of the repeaters with this setup. I have absolutely NO problems with transmission or receipt in town or on trails. Hope that helps!
