If you want an EFHW, but you cannot afford a kit, or a commercially available product, maybe consider building your own.

Why build your own kit?
1. Knowledge - Sourcing parts and building an End Fed Half Wave Antenna SHOULD get you the same knowledge as buying a kit, but also allows you to learn how to shop for deals (a good trait to have)
2. Cheaper - Building an EFHW from scratch WILL be cheaper than any commercially available kit
3. It's like burger king - Have it your way
4. Creative freedom

_______________________________________

In this episode, I go over the main components in an EFHW kit, and I discuss sourcing out parts, where to look for certain things and how to find great deals on efhw related materials.

I do have affiliate links here to some products (listed below), I would advise you to do your own research and searching (ebay etc) for cheaper parts. As the internet is EVER CHANGING, so are prices. Today my suggestions and prices may be different than tomorrow. I am simply providing suggestions for you to learn how to source things out (teach a man to fish).

Honestly, just check out his whole EFHW series. Collin Also conducted research about windings and transformer efficiency - https://docs.google.com/spreadsheets/d/13kImt_tkezngocXQ5tOBDkTscp5F-RFD/edit#gid=2134716366

I do HIGHLY recommend building your own EFHW once in your life. However, if you do not feel comfortable yet, it's okay (you'll get there): I recommend X-Tenna's antenna for the switchable capability and because it is already built (with quality) (non affiliate link, however if you do buy one, please let them know in the notes that you found it from HRD) - https://www.etsy.com/shop/XTennaAntennas
