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.
