Hey /diy/,
I want to make a CB radio manpack (pic telated). I'll be using two lamp batteries wired in sequence (?) to produce the 12 volts of power needed.
Now, my question is:
If i were to hike to the top of a large hill in a semi-urban area and attach a magnetic antenna to a large powerline tower (one of the triangular
/pyramid like ones usually found in the countryside/hills), what would happen? I read somewhere that if an antenna is touching a large metal structure, the structure turns into an antenna. But would the power lines have any effect?

I really don't know where to start with what is wrong with this line of thought.

I think you mean 2 6 volt batteries wired in series? They aren't going to last too long. Try a 12 volt 7ah ups battery.
No attaching an antenna with a magnet to a high voltage power tower will NOT turn it in to an antenna.
Yes the power lines would.
You really need to rethink this whole thing.

that is not a CB radio.

to be precise that is a HAM radio antenna tuner.

Use an SLA instead I guess.

They use F cells. They were common in old fire tower radios.

As for CB antennas better of making an end fed half wave to hang from a tree.
