The Build-A-Thon is FULL: All 10 spots have been taken and we have 3 on the stand-by list. So for now the list is closed.
This year’s Build-A-Thon will be a 67-foot EFHW to be built from a kit. The Build-A-Thon will start around 10 AM on Saturday morning in the Exhibit Hall in the Exhibit Area.
After receiving dozens of inputs, we went with an antenna that is:
- Easy to build for a first-time antenna builder.
- Lightweight for POTA/SOTA adventures.
- Stealthy for those with HOAs and/or nosy neighbors.
- Uses a 49:1 Unun Impedance Transformer built on a 240-43 Toroid suitable for power levels up to 250W SSB or 100W CW or 100W Digital.
- After tuning, this antenna should be resonant on 40m, 20m, 15m, and 10m, with an SWR below 2.0 across the entirety of all four bands.
- Includes 67 feet of #22 Poly-Stealth, High Strength Aerial Wire that is; 19 strands of copper-clad steel wire in a tough PE (Polyethylene) abrasion-resistant jacket.
- We will show you how to add a link to make it resonant on 30m as well.
We will have 2 Instructors and various Elmers on hand to guide folks through the process of building this kit.
Limited Class Size: We only have room for 10 builders and each kit will cost $49 which will be payable at the Build-A-Thon or you can pre-pay using PayPal. An email on how to pay via PayPal will be sent after registering for the Build-A-Thon.
