Hi Leo,
Although the HF-Pro-1 is still available, I recommend you look at the Komunica Power HF-PRO2-PLUS-T. That “Plus-T” is significant as they have changed the design from using two pieces of metal rod with an Allen screw tightened joiner, to using a telescopic element instead. As well as making transport and assembly much simpler, it also adds the ability to use the antenna (in a pinch), on VHF bands as well, as a 1/4 wave or 5/8 antenna. With the supplied add-in loading coil, and hand adjustable coil on its base, it covers all bands from 80m through 2 metres.
My review is here: Komunica HF-PRO-2-PLUS-T HF portable vertical antenna. | DD5LP / G8GLM / VK2JI blog
In the UK, it’s sold by Lamco in Barnsley - https://www.hamradio-shop.co.uk/product-category/komunica/
If considering using any of these antennas portable, you will need a base and radials. I built my own using a small photo tripod but Kommunica also sells a tripod with radials for the antenna as an accessory.
