13m long vertical Antenna for 160-10m

Inspired by M0AWS’s blog post “Easy Multi Band Vertical Antenna for HF”, I’ve converted my 40m quarter wave vertical into a 13m long random wire antenna which is tunable for 160m up to 10m. The antenna system consists of:

• 12 Spiderbeam HD fiberglass mast
• 13m of wire, the top 1m tucked into the upper most mast element
• Two 3D printed mounts for the mast (details here and here)
• CG-3000 remote antenna tuner
• DIY mounting plate for the ATU (400x200x2mm aluminium plate + stainless steel mounting bracket)
• ca. 30 radials with lenghts of 1m up to 5m
• 2m long ground rod

I have had very good experiences with the aerial so far. It tunes on all bands from 160m to 10m without any problems with two limitations:

• On 80m I only get a match of 2:1
• On 15m I only get a good match if the first tuning process on the band is carried out in the lowest band segment. After that I have a very good SWR over the whole 15m band

Here’s a picture of the antenna in it’s full half glory:
