TowerTalk is for discussion of tower and HF antenna construction topics. Your question seems appropriate. I knew it would happen sooner or later. It old age creeping up. SRI 73 fer nw, Bob AD5VJ(AAR6

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
Many thanks to the guys that responded. I have some good leads on this now. 73, Jerry K3BZ webpages get Weather Stations", and lot's more. Call Toll Free, 1-800-333-9041 with any questions and ask fo
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

I see MFJ is selling Franklin 2 wavelength collinear wire antennas. Has anyone had experience with this type of antenna? Bob W2WG Alan, The double bazooka (as conventionally described) is a waste of
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
Go here: http://members.aol.com/homingin/MoreSQuad.html. That has some infor on the bazooka balun. You can Google it and find a bunch of webpages about it. 73 Tom w7WHY ______________________________
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.
Hello everyone: I am in a space limited environment and already have a double bazooka tuned for 80 meters that works fine on 80 meters. I also have a MFJ-949B Tuner and a manual antenna switch. Rig i
Well I sent this to TopBand Reflector first but no one has responded so I guess I stumped 'em. Hello everyone: I am in a space limited environment and already have a double bazooka tuned for 80 meter
Alan, The double bazooka (as conventionally described) is a waste of "weight". It will not outperform an ordinary dipole in terms of gain (it has extra loss, which is where the minor VSWR bandwidth i
Velocity factor for pretty much any transmission line (including a single wire) immersed in a dielectric is 1/sqrt(epsilon). Something with a polyethylene dielectric (epsilon around 2.2 to 2.4) will
Tom...read your website, thanks. I'm looking for a good balun at 6M. I suppose a 1/4 wave length of braid from an old section of large-diameter coax could be slid onto 50 ohm coax feedline, but you s
Peter. Wow, another lightning topic! Seriously, the Bazooka is VERY bad theory that gained mainstream acceptance through word-of-mouth and misguided advertisements by people marketing them. My first
Hi Tom, Just to add a few words. In the early 1980's, Frank Witt, AI1H, was doing lots of work on broad banding 80-meter dipoles. He first explored the double bazooka and concluded it was slightly wi
Some years back I ran across a similar roll of around 200 feet of RG-6 on a small wood drum at a thrift store in the valley. Looked like it had been there awhile so made a ridiculous offer which was
As I mentioned to Tom privately, W8JI has some notes on his website regarding this topic. The idea of "shielded conductors" having better noise performance is a myth, and is typical of those that (as
