Feeling out Antennas for K9ZW Island QTH – Part 1

A lot has been happening at the Island QTH – the biggest is the ongoing Garage Building project.

Garage 16 June 2018

And just as importantly the first non-temporary antenna will be going in – a Zero-Five custom extra-heavy-duty Flagpole Multi-Band Vertical antenna.

The concrete base should go in at the same time the garage apron slab is poured.

Zero-Five made two extra-heavy-duty custom antennas to meet my wind/weather special needs. The have tilt-over-bases and a loading-balun for 80m.

One of the two Zero-Five made is reserved for my home QTH to be installed later this year or next spring. These antennas truly are also functioning flagpoles, though I wonder what might happen to a flag when running an amp?

The trenching contractor in the island is running a 4-inch buried conduit to the antenna, so I can both bury a feed-line, and run power to lights for the flag.  I may eventually experiment with a remote antenna tuner at the base of the antenna as well, and the conduit makes adding internet easier later.   Ideally it would be nice to separate the different cables, but as most trenching involved breaking out bedrock I will have to settle for a single conduit and go with the best shielded cables available.

To work well this model requires buried radials, and eventually lots of them.

Because of the bedrock the usual base has been redesigned to make best use of the “rock solid” situation.
