- A coax just a little bit shorter than a quarter wave shows a VERY quickly changing inductive reactance ... so you can change the stub length +/- a few centimeters and find the exact value of reactan

- Dan, You got there before me! This design cannot work satisfactorily as shown. Not only are the "integral stubs" very lossy, as you point out, but the Reflector is totally "closed" (inner and outer s

- David, you have the right approach. Pardon me for saying it, but it is a good idea to consider anything by N0KHQ (and most of the other stuff on HamUniverse) with very cautious skepticism. He has som

- David, I don't see any connection to the shield of the coax used in the driven element or the reflector (see drawing, "Center Conductor only is attached to feedline on both ends!"). It looks to me as

- That is correct and is exactly why a double bazooka is shorter than a normal dipole. I have looked at the pics and dont see why the antenna would not work. Whether it works as advertised, who knows u

- It does work, in a way. The radiating elements are the *outside* of the coax shield. The *inside* of the coax shield and the center conductor form a coaxial stub that's in series with the outside. I

- All that Dan says, plus...... ...... the Reflector has the Inner and Braid shorted at both ends. There is no way for differential-mode currents to be excited in the Reflector coax so there can be no

- Thank you all for the response. I made one dipole for 10m band with RG8 type, vf=.66, formula dictated about 1.75m for each half of the dipole. I started with 1.80m per side, and hung it about 2 mete
