Description
This is a modified version of the 40M Digitenna by DigiRig. I have widened the spool by about 10mm and added a loop to hang the reel from. This allows you to fit stacked FT-82-43 toroids instead of the single one of the original design. Which gives you more power overhead room. The loop makes it easier to deploy.
