It's ok to use steel/iron wire instead of copper?
Feeding it directly to the the sma connectors (like hugeone did in the photo) can cause problems?

What's the best match on the receiver side (fastshark googles) for one of this on the air/ground? (keep in mind it must be small and light not to bother when you wear the googles)

I use copper clad steel welding wire for my mig welder. It works great.

For 5.8GHz, the tolerances are very tight. However, the antenna is wideband so you don't need to be perfect. Just get it as close as you can.
