Well there is a good reason for that low antenna. Keeping it out of the branches while off-road keeps it from getting broken as most are constructed from fiberglass. And as you know, better made antannas aren't cheap. Adding a spring just whips the antenna back into the body or top and either scratching body components or again, breaking the antenna. Many new off-roaders (first time radio owners) see and try to emulate others without understanding why their gear isn't as effective on the roads as in the woods.... It is a trade off they don't understand right away and like you say, might complain about their setup ignorant on why they can't reach longer distances out in the open. My CB antenna is as low as I can get too but I understand the SWR and reduced effectiveness and live with that as it serves the purpose I need it for. It's OK if you snicker at me when you see me driving down the road with my low-riding antenna but; don't try following me where I go, you won't make it. So far my GMRS setup isn't as good as my low riding CB either. In the rain traveling down different roads we got better distance and clearity out of the CB's than we got from GMRS radios. But I am on my own and new to this so I can't snicker at anyone while I am still in the learning phase... Not all that wander are lost!
