just my two cents:
1. I mostly use the 5m and 6m mast from lambdahalbe.de. They work very well with all kinds of wire antennas, including my SOTA vertical with 3D-printed parts: https://www.thingiverse.com/thing:2450117.
Whenever space permits, I carry the 6m version, because I feel without any systematic analysis that the additional 1m matters in terms of performance. I managed a 10,000km contact from SV8 to Japan two month ago when propagation was unusually good.
The downside is that the mast is 600+g and thus a bit too bulky for my taste.
- I have now ordered the 5m version of this carbon pole:
It is currently sold out in most shops and supply is announced for January. But then, it might be the ideal rod:
- less than 200g
- 38cm transport length
The conductivity of the carbon might be a negative factor, but I hope it will simply detune my vertical a bit, and will be with no major effect for my inverted vee / EFHW antenna.
