I think it is a combination of several concerns. One, CBs maybe considered distracted driving and that is a big buzz word now. Two, as stated elsewhere, company owned rigs may not be allowed to 'modify' the rig. Three, cell phones are easier to use and you can talk to who you want. Four apps like Waze and Radarbot give decent bear reports without all the extraneous el toro poop.
I'm on road trip this week and I've been looking at big trucks as we pass. Well over 60% (rough guess) no longer have a CB antenna on their rigs that I can see.
But at a couple of slow down/stops for whatever reason, 19 came to life. Maybe truckers have a handheld for such cases. But driving along, my rig will scan all 40 channels and other than the perpetual ratchet jaws who love locking up a channel, pretty dead.
One question though, when did channel 9 become the Spanish language chit chat channel? I've traveled through 7 states and in 5 I've heard 9 locked up with Spanish conversations.
channel 9 is now the Spanish super bowl in some other country... or countries.
the new generation of truck drivers don't care about having a CB, so very few on trucks now. and if you do see a CB antenna it's a 3 foot tall piece of junk that only works for a couple miles... with such a lousy antenna they learn that their CB's can't communicate with anyone out of sight and they just figure no one is on CB anymore and shut their radio's off.
people buy the cheapest CB and antenna they can buy... like a $34.99 CB off Amazon click this like--->
$34.99 CB Radio if you read all the reviews ... no one say's they talk to anyone on the reviews.... most say I love this CB it's small and fits in a tight spot in my car... I have not talked to anyone yet as I bought it for when SHTF..... others say I have not talked to anyone yet but I can hear people easily on Channel 6, 9, and 11 so this is one great CB????? I read thousands of these reviews from cheap CB's and cheap Antenna's... it has killed the hobby--- in my opinion!
as you said all the new programs with GPS and traffic alerts have replaced the desire for CB's
for quite sometime now ( years?) skip has pretty much shut down channel 19.... so people turned the squelch way up high so they could only hear very close vehicles.... but then people with mega watts CB's ( like the guy in the desert ) would broadcast non stop making people on 19 just shut off their CB's...
manufacturers made little 3 foot antenna's like the Lil Wil, K-30, Tram 300, Cobra HG1500, Hustler IC100...... people didn't want to put a big 5 foot tall magnetic antenna on their roofs so they bought those little 3 foot ones... then they would make a contact about 2 miles away on a busy highway near a truck stop.... or hear people on channel 6 ... or hear high powered skip from these 60 plus watt ham Radios or Export Radios and think their CB is working fantastic! then they would review them on Amazon.... and before you knew it, there were thousands of 5 star reviews from people that never even made a contact, but were telling the world that these 3 foot very limited range antenna's are the great thing on the planet......
so next thing you know people read all the reviews and buy a 3 foot antenna and the few CB's that we do have on the roads today can only reach out a little more than 3 miles if that.....
because of the poor antenna's limited range, on a road trip the CB becomes useless and they take it off the vehicle and sell it or give it away and never use it again as they say CB's don't get enough range to be worth having them anymore.... or they say CB is dead.....
if they had only tried a good Stryker SAR-10 antenna they probably would be talking to people in a 10 mile radius!
these 3 foot antenna's makes it very difficult for all of us to actually find someone on the CB when we need someone.
if those little 3 foot antenna's hadn't been made... and everyone was forced to buy a Wilson 1000, or a K40 or Stryker SAR-10 they would be getting 5 to 8 miles of range and I personally think we would see a different hobby than we see today.
just my opinion why very few people use CB radio's today
