Vertical dipole construction - aluminum tubing vs wire

Planning a 20m vertical dipole for portable ops and debating materials. Aluminum tubing offers telescoping convenience but I'm concerned about bandwidth and mechanical complexity. Aluminum tube provides broader bandwidth compared to simple wire but costs significantly more.

Wire is cheap and proven but requires guy lines and careful support. Looking at a fiberglass pole setup similar to what I've seen in POTA activations. What's been your experience with both approaches?

The major advantage of aluminum is the ease of nesting telescoping sections for portability. I've built both types and for serious portable work, aluminum wins hands down. Yes, it's more expensive initially but the time savings and reduced setup complexity are worth it. My aluminum vertical goes up in under 5 minutes.

For QRP POTA work, wire is perfectly adequate and much lighter in the pack. I've used a wire vertical doublet on a 12m fiberglass mast with excellent DX results even on QRP. The bandwidth difference is negligible for single-band operation. Save the money and weight - go with wire.

Started with wire verticals as a new ham and they work great! Don't let anyone tell you that you need expensive aluminum to get on the air. Dipoles are one of the easiest antennas to build for HF radio bands and achieve top-quality performance levels. Learn the basics with wire first, then upgrade later if you want.
