If you use an all 1" diameter element it will resonant lower than one that is 3/4 and 5/8. I used the W6SAI Beam Antenna Handbook to run some figures and looks like the 1" diameter element should be about 1/2" shorter than the original.

My aluminum supply is somewhat skimpy and I was wondering if I could replace the entire first director with a single piece of 1 inch tubing; no taper?
