nonsence,band 3 has 8mhz channels,used on the continent,frequency doesnt determine bandwith until you drop to lf,band 1/2/3 have had tv on them,new zealand uses 45mhz,channel,australia used to use band 2 for tv,,dab in mono is probaly for other reasons, on band 3,bandwith isnt a problem,in years gone by,belgian tv used 11.15mhz,819lines on band 3.n..............

Ray Earl: ,its possible the coax has degraded so you have to do an overhaul,buy an set top and see what reception is like otherwise its up on the roof i'm afraid,n...............

Hi,you could check reception with a second hand fv box or overhaul yr aerial system,try a set top aerial and see what local reception condiions are like,sometimes the tuners go faulty after a number of years.Myself,i'm lucky,i live in a swamp area.

Hi,there is another way to improve reception but it is only open to those who can use a soldering iron and are capable of doing work on aerials.n............

dear mike,australia used band 2 for tv broadcasting for many years,also china i think also uses or did use band 2 for tv,i'm suprised you don't know this.n.............

Hi,one way of improving yr reception is to remove the aluminum dipole which has the coax cable attached to
it and replace it with an insulated thick copper wire,bent to the shape of the dipole,yr aerial should pick better,copper is very good for aerials,as a instance,north of oxford,on a set top aerial, i can get a locked
picture from hannington,abt 40 miles south,before it was 5percent on the signal strength.This is done at yr
risk,NO legal responseibilty of any kind accepted.You might find the signals too strong,worth a try if you're up to it,don't do anything you can't cope with.

MikeP: This is the basic construction,you would need to protect the the wire,etc,theres corrison between the copper coax and the connections,in all aerials after a while,i have had an aerial last over 8yrs,the wire needs to be the shape of the folded dipole but so long it looks like it,it works,sorry all aerial fittings are subject to corrsion but the advice is for people who can handle same but where theres a problem of marginal signal pick up its worth trying it,i have an set top here cause the field strength is high enough not to need an aerial.The information is for people who are able to do the work,n............

Sorry,as i said,if the pick up is still proving to be difficult,its a good solution,if preamps will be affected by the mobile phone system prove to be cointerproductive.If i can get a locked picture from Hannington at 40 or so miles on a indoor set top aerial then it works,all the others gave me 5percent on the box,n.............

MIKE,i go by experience,some will implode,some will explode,you will not know until the moment,no matter what,being next to a tv tube whether it implodes/explodes,isn't the place to be,you want to remain top dog,what more can i say.I am sure you didn't put yourself in the firing line when you tested the crt.No one in their right mind would hit a crt with any hammer,implode/explode,the glass is going somewhere,you are flesh,it doesn't mix with flying glass............n
