While some graphics seem to show alternates (radio was changed several times, apparently) the most definitive drawings of the Dreadnought show a "barrel" shaped antenna, where there was a central conductor surrounded by eight other conductors, held in position by a group of snowflake-shaped structures. I assume this cylindrical array increased the bandwidth allowing some choice of frequencies. Anyone know what they actually called that style antenna?
The Pontos detail set does provide those separator/supports, and I have built a jig to try and make the four arrays needed. First attempt doesn't look good- made with monofilament. Second try using regular twisted fiber (multistrand) thread looks much better. Will have to rescue the insulators from the first attempt- there are not enough spares for a whole extra array. The Pontos set gives no instructions or drawings of the antenna, but support folks have given me from forums gives me a good idea of what the size and arrangement of the array is- now I only have to make them!
