This is post 2209 in a continuing series of simple ham radio antennas.
If you're using a vertical HF antenna, you know the importance of establishing a good ground radial or counterpoise system.
In this well-paced video from Callum (M0MCX), we see the ground radial project taken to its reasonable limit, with almost 405 meters/1,329 feet of wire prepared to insure an efficient radial field.
If you have lots of room and want to improve the performance of your HF vertical antenna, then this is the way to go.
Here are some general comments from Callum:
I used Arctic Grade DX10 for these radials for my eXtreme Nebula multi-band vertical currently in development. These 45 x 1/8th wave radials are equivalent to 22 x 1/4 radials for 80m; 5 x wavelengths - and a whopping 10 wavengths on 40m. Heck.. that'll give me 20 wavelengths of radials on 20m! And on the higher bands, I'm aiming for 5/8th elements so it should be pretty good! I am very excited about this antenna! Callum. M0MCX
