i have recieved MURS stuff at relatively long ranges in the woods. there are some high end motion detectors you can buy that will tx the alert on MURS. "Alert Zone Two...Alert Zone Two" in a soothing female voice. i live on 30acres with no clue how far away its coming from, as my closest neighbors seem the least likely to have such things set up. i estimate its at least a mile away and through solid woods.
since you mentioned camping and are willing to tote bulky things like a handheld CB, then you'll love my next idea. assuming a bnc connection:
short part-
bnc male connector-short length of wire-allegator clip/bullet connector
long part-
long length of wire-allegator clip/bullet connector
wrapped/taped/twisted around a multisection fiberglass tent pole
type with elastic cord thru center

ya just unfold it, hold in hand (or my favorite, put one end in a pants pocket) clip antenna to radio and you're set.
i found some discarded on the beach years ago that were over 20ft long, most are way shorter, but ya have options.
either way it loads of fun and the chicks dig it. go ahead try it out, you'll love it. $10 cost, 10 minutes effort, and you'll be knockin squirrels outta trees in no time.
Side Note:
being unsurprisingly disappointed in BNC handheld antennas for CB/Low Band has me still pursuing one that is at least decent-ish. best so far i have found is the W-881 Portable Antenna. anyone have suggestions?
i don't care about length, it just can't be so heavy that it puts serious strain on the radio, and it needs to be flexible enough that i can smack it into stuff on a regular basis, making a telescoper unsuitable. it has to be bnc cause i don't need a bunch of adapters adding to the strain.
i have had no success in locating a Comtelco PEXL36 BNX (BNC connector) as the few who offer it for sale turn out not to have any. mentioned here:

anyone know where i could get one, or similar, from a non-overseas supplier?
