Most organized offroad events and 4x4 clubs completely banned 102" whips years ago. They did that because they have a history of whipping about and occasionally injuring bystanders, especially after they pull free after having had their tips tied down or tucked into various parts. Some have even banned antennas over about 50" for similar reasons. For the most parts, tall CB antennas just aren't needed when offroading. I have been successfully using a 2' antenna for 13-14 years after starting with a 4' then 3'. That's even with much of my wheeling being in canyons and mountainous terrain, often while leading large groups of Jeeps around. If the Jeeps furthest away at the tail end away from me couldn't hear me well at all times I wouldn't still be using my 2'.
