As a winter storm moves through I’m assembling an experiment based on the cage monopole idea discussed earlier. This will be indoors for obvious reasons.
It’s easy to visualize a physical antenna array in the head but never so easy to make it stand in space all by itself, so I’m using bamboo poles to build a tripod growing out of a triangular base made of pressed board, using wood glue and round-tooth-pick-dowels.
The tripod is around 6-feet standing up on top of a 30-inch wooden stool. Maybe a few tiny screws will add security.
I’m doing FM with the Whole House 2.0 because of the more convenient lengths, and first will try a three wire cage, branching from a common feed point at the bottom, then try a four wire version. At a later stage I’ll add some ground plane elements pointing out horizontally to see how that changes things.
I can make fast excursions out into the freezing wind with a portable, but also indoor improvements are easy to notice since FM indoors doesn’t do well from room to room.
I’d had this three-leg-bamboo tower put up before, but the glue popped and it fell with a lot of clatter. This time more attention is being spent on securing the construction.
