O2 masts

[Anonymous]

I have often seen them, but don't know much about them. I have just used ofcoms search, to find out if there is one near me. There is an O2 mast, less than a mile away from me, that has 4 trasmitters. 2 x 900 1 x 1800 and 1 x 2100. I'm going to assume this is good... I believe 900 is good for 3g indoors? Anyone give me some insight into this? 

ta!

I remember back in the days making the BT Cellnet & Vodafone masts there where about 256 individual solder joints on each one with wires everywhere, the Voda one's where more fiddly to assemble.

Then the new UMTS mast came out with just 4 solder joints, everything was just clip / snap / screw together then solder the 2 sets of connector leads on.

I loved soldering at school, not sure I would like to do 256...

I too enjoyed soldering at school:) was a shame when H&S kicked in and we all had those ruddy vacuumes attached to the irons. Sucked off the solder before it had a chance to cool. What use is that haha.

The on iron vacuum extraction is pretty useless, the tube always gets blocked up after a few hours.

I found the Plymovent extractor system mounted directly on the workbench much better.
