I played with the Hustler when it was introduced, and got the impression it
was a loser 40 years ago. I now wonder if that lower mast is purposely lossy. Or maybe just accidentally lossy and they ran with it. Looks good on SWR meters which hams are infamous for. I would modify your observation about the diameter of the bottom section to: The RF impedance of the lower section really counts. How about trying either a copper braid or tube around the Hustler or a copper plated base section under the bug catcher and see what that measures. -- Crazy George Remove N O and S P A M imbedded in return address "H.

So here I present the resonant feedpoint impedances of a Hustler (small resonators), the Tarheel 200 screwdriver and a 103" whip on a bug catcher on a 54" Hustler base.

The screwdriver shows encouraging results for signal improvement over the others on 80 and 40. Seems the diameter of that bottom conductor on the screwdriver makes a big difference at the lower frequencies. Since the TS-480HX has two antenna jacks, I think an additional small screwdriver is in order; One for 80-20; One for 20-6. 73 H. NQ5H |

Building an antenna using a big copper pipe for the base is appealing.
It's the motor tune feature on 80 that attracted me to the screwdriver. All a low SWR insures is that you aren't heating up your transmitter. I use a field strength meter. 73 H.

Or maybe just accidentally lossy and they ran with it. Looks good on SWR meters which hams are infamous for. The hustlers I tried had pretty lossy coils. I've never seen any problems with the solid masts, but I've never tried the folding type. In theory, they should be ok also, unless they have a problem with dirt or corrosion. But the coils.... I hate those things....I once did a comparison using a large 80m resonator against the coil on my homebrew plastic bugcatcher. It wuz ugly...My homebrew coil was much less lossy. I'll never use a hustler coil for anything serious. And being I'm always serious, that means never... :/ MK |
