I have an old antenna that I used when I had a company radio in my truck years ago. I don't remember what part of the spectrum it used. The antenna length is ~59." Using the 468/λ=Length (in Ft), I then solved for what I knew: 468/4.958(antenna length in Ft)=94.38λ(in MHz). Then I divided 300/94.38 and got 3.14 (3 meter band).
So, if I did this correctly I don't think I can use this antenna for 10 meter of 70 centimeter with any reasonable level of efficiency. Please comment and feel free to correct any sloppy logic.
