Kevin, I agree that being able to bring the SteppIR down to ground level is a big help. I have owned a four element SteppIR Yagi for seven years now and also have a BigIR vertical. I like the antenna

Dear OMs and YLs, Yes all this is true but do not forget the actual radial length will be shorter than 0.4 Wavelength when on the ground. It may be electrically 0.4 wavelength but physically it is co

Rick, What you are saying is correct a short vertical requires a lower ground resistance for optimal performance and thus a more extensive number of long radials. Otherwise there is further compromis

Jim, Thank you, I may add some longer radials. There certainly is much confusion and conflicting information abounding when it comes to radials. In some cases this may be due to inadequate care taken

You can also obtain electric fence insulators with a screw end and put them into your trees. I have done this with good success. Just take them out when and if you remove your antenna to prevent them
