IIRC, if you take the square root of height in feet and multiply that by 1.4, you get your "radio horizon." (I got that from the "Radio Handbook, First Edition," 1935) So if you have a 100 foot antenna, take the square which is 10 and multiply that by 1.4, you get 14 miles. Of course, lower VHF frequencies might go further plus you have weather and ionospheric conditions too.
Sorry I haven't been around as much, Mom is fighting inflammatory breast cancer, Stage III and is on chemo now. I'm optimistic though, it is a well researched disease and I've run into many women who have kicked it at even Stage IV and/or living while managing it. I talked to one lady who had it for 10 years and been on chemo for 5 straight years and is still going but I'm hoping for my Mom to kick it. Sorry for hijacking the thread but I've been scarce lately.
