Anyone know what the problem is here?
My boss’ 8wheeler has a Thunderpole T1000 rig and a short stinger aerial mag mounted onto the roof (CF). It’s become impossible to hear/transmit on the lower channels (we use 5 in a local tip) but 36 was working fine until this afternoon. It is on FM and despite these problems, I can still here “Radio Stalingrad.”
Any suggestions?
I cannot offer solutions, Muckaway, but I will try to tell you what is happening.
The aerial, to make 8.5 ft into a workable length, part of the aerial is a coil, this reduces gain (get out ability) and reduces bandwidth the aerial can happily transmit on (there are other factors, too complicated)
Olga will come through because “skywave” can be a very strong mode of propagation so you are stuck with her until the 11 year sunspot cycle comes back down to minimum in another 3 or 4 years.

It’s still legal to use a two way radio, ie CB, which is why taxi drivers can use them.
Like I say.Have’nt used one for years now.So was just wondering if the law had changed on them at all.Clearly not though.
That is true, however there is the catch-all law, “Driving without due care and attention”
There’s more Americans on it than anyone else
get an swr meter on it nathan and adjust the whip length until it balances on all channels . alternatively , bin it and get a decent twig .

I think it’s the aerial too rigsby. I had a similar one on my last loading shovel (so it didn’t het damaged going under conveyors etc) and it’s range was hopeless.
I had the standard height stinger mag mounted onto a Scania P cab in my last tipper job, and even with a budget rig I had very good reception.
I’m driving the boss’ truck on Monday and I still have an old mini Allen key so I’ll climb onto the roof and have a go at it. If I can sort it I’ll get my boss to fit one in my wagon.
Coax fed through the door or sunroof opening? It’ll be crushed by now I’d have thought and effectively shorting out.

Nope, checked for that mate. Fitted through the roof properly, but with a mag on the end.
I had a coax fed through the door of a Foden 3000 and never had a problem. That was probably down to the door not shutting properly I expect.

In your opinion, they are very handy on tippers delivering tarmac to road works inc night closures, having a phone is not much use if you don’t have the no’s for anyone on site, the quarry run on the same channel so someone will have their “ears on” that’s the whole point!
missing an access point can mean going miles out of your way, once on the job you can be held in a parking area out of sight of the gang laying the stuff, a driver tipping will shout the next truck when needed so you don’t get everyone parking in the way blocking the job up!
other technologies don’t yet work in this area as planning in advance wont account for changes that take place on most jobs
It works well in quarries if the shovel driver has a cb. You do have to check which mic you pick up as in my case, I bawled out some politically incorrect comments about our travelling tarmac salesmen, only for it to be broadcast over the company two ways. With management listening. 
I just said the need is reduced I didn’t say the chicken box was unneccary

Two reasons for that.
(1) The vast wide-open spaces over there means there are large areas not covered by their mobile phone network
(2) The propogation (skip) is long which favours cross-pond and (unfortunately) Central Russia (Unless you want a taxi to Vladivostok)

essential piece of kit today if your running in out of Ireland north or south.(running legal or bent) bent is more fun though…you have 100 miles of the most anti truck road in the uk…A75 ,followed by the A55 and A41 …anyone running these roads/ferry ports will be on AM cb. theres no point in fm,as all the irish are on a.m.simple as that,and itl save you a fortune in hassle knowing what vosa checkpoint is open or closed etc.all that is a bonus though apart from the craic of the mad paddys or Donegal mafia flat out off the boat heading for carlise flat to the mat the whole way.( which will be well in excess of the poxy 90k your meant to be sitting at)…running with the pack at 65 mph in a 40 zone for 100 miles certainly helps to combat driver fatigue,as well as the obligatory overtaking on the cb from the guy in front round the blind bends etc…oh the joys…
Your not wrong DD. Always remember when I was on agency for Woody’s night trunk I met the “pack” coming south at Dunragit 4 m bridge on A75 nearly put me in the bridge wall. they will drive that road like its one way.
A lot of the old bill had them also on A9 and A74 especially the Sherrif of Lockerbie… PC Little!
