Based on the performance data (K7LXC/N0AX) for the original Force 12
C3 and TH11 with comparisons of the broadband Hexbeam and the TH11.
The K7LXC/N0AX field data shows the C3 outperforming the TH11 while
G3TXQ's web page <http://www.karinya.net/g3txq/hexbeam/broadband/>
shows the TH11 with approximately 3 dB advantage over the broadband
hexbeam.

Neither the XR5 nor the Navassa 5 has 11 elements *or* capacity hats.
The XR5 is a 9-element antenna and the Navassa 5 has 10 elements as
documented in the two links I provided.

The point about uv is well taken re fiberglass, but I don't know what the cords
on all the hexbeam versions are made of. There are uv resistant materials
available.

Can anyone with a hex beam comment on this?
Your concerns are well placed with antennas made of fiberglass and
dacron/kevlar cords.
Instead of a hexbeam, I would recommend looking at the Innovantennas
XR5T:
<http://innovantennas.com/antennas-a-accesories/on-line-shop/view/productdetails/virtuemart_product_id/435/virtuemart_category_id/55.html>,
or the JK Antennas Navassa 5:
<https://jkantennas.com/jk-navassa-5.html>
Both have boom lengths of 12 feet or less, cover 20 - 10 meters and
have optional 6 meter add-ons. Either should significantly out
perform the hex beams and - since they are aluminum antennas that do
not use UV sensitive fiberglass, kevlar and dacron components - should
significantly outlast the hexbeam with significantly less maintenance.
