[TowerTalk] Beefing up Aluminum Beam Elements

[Dino Darling]

You should have this book!!!

http://www.universal-radio.com/catalog/books/0995.html

It can answer all your questions!

Adding mass to the inside of the element will not change your SWR, but may 
cause your element to physically fail.  There is no easy answer to your 
question!  Buy the book and get some help with the math if you need to.  It 
is an EXCELLENT resourse!!!!
