Hi,

I'm new to amateur radio, and am looking to build my first antenna for
the 2m band. I intend to build the one at http://www.qsl.net/iz7ath/web/02_bre...ole/jp_eng.htm.
As this is my first, I have a couple of questions about it's
construction:

1) Can I use copper tubing instead of aluminium?
2) Are the tube diameters crucial?
3) The instructions seem to imply that I can use the longer of the
tubes to mount the antenna. Does this need to be insulated?
4) I'll be using the 2m band, max power 10 Watts, and a cable run of
no more than 20 meters. What sort of cable would be best fro the
feeder? (Ideally one that can be purchased from Maplin:

Thanks.
