Digitenna

Easy to use compact and lightweight endfed antenna for HF bands.

• Deploys in seconds – ideal for POTA activations and preparedness scenarios. Requires use of mast, tree or another raised point anchor point.

• BNC male connector. Short run of coax is required for connecting the transceiver. Coax shield acts as counterpoise to the radiating element

• Tested up to 30W with high duty digital modes operations, should be good for up to 50W on voice

• Comes with 10m of silicon insulated 22AWG (random colors) – tune it for 20m and harmonics (10m, 15m, and 40m) by shortening or partially unwinding

• S-carabiner to connect to the anchor point

The parts normally do not require support structures.

BOM:

• 3D printed parts

• 24AWG magnetic wire

• female BNC connector

• 100pF 1KV ceramic capacitor

• FT-82-43 Ferrite Toroid Core

• 3x M2.5 flat had screws 14mm length

• 10M of ~22AWG insulated (silicone recommended) multi-thread wire for 20M band. For lower bands use 20M length of thinner wire so it fits on the spool.

• Small S-carabiner

2-26-2-26 UPDATE: Uploaded refreshed files for the original 20m band variant with several small improvements. Also, by popular demand added files for 40m band variant. Use 20.5m (67ft) of 26AWG wire for 40m band option.
