The "broadbandedness" of the double bazooka probably comes more from the additional loss of the coax than from any increase in the size of the conductor. If you consider the size of 12 gauge wire or

I use full-size Double Bazookas on 160m and 80m, they actually are not bad on bandwidth. The 160m certainly has greater bandwidth than the Carolina Windom that I had up and is quieter. I adjusted the

Well.. I'd be more optimistic.. Use PVC for RF (I do all the time), but test it first. Mostly, you're worried about loss. One way is if you have an air core inductor that you can measure the loss of

I think Tom and others will tell you that the double-bazooka is very lossy. It has had widespread use over the years, but if you read the literature on antenna efficiencies you will see that a random

My store bought bazooka was quiet - both noise and signals. My 80-40-20 fan dipole works better. A tuner matches the feedline Z at band edges and 80m coax swr losses are very low using RG8 or better.
