LOWES AND TRACTOR SUPPLY
Yes i have and it was a load of crap..never again..
I'll stick with my monoband antennas if that's ok with you..
Nope. Anything that conducts RF power is antenna. Good or surrogate, whatever. Radiation of an antenna does not depend on resonance but on current distribution in it, and losses caused by resistivity of real counductor, of the ground (where applicable), and so on. Radiation/losses ratio is measure of antenna efficiency.
Dummy load has almost 100% losses (intentionally) so it has steady impedance within its working range. Obviously dummy load would appear as resonant antenna on any frequency so useless for tuning the amp for a real (imperfect) antenna at given frequency (where particular impedance may vary).
Matching may be wanted due many reasons but this doesn't mean the antenna itself has to have resonance to radiate efficiently. Sure one can tune rusty nail and call it 'antenna' but its efficiency is still radiation/losses ratio, not the resonance.
An end-fed half wave is way less expensive and easier to use.
You're focused on too many inconsequential things. In most of the views of the radio, I saw full power output. If the radio is putting out full power, then be satisfied. Focusing purely on SWR is wasted effort. Too bad the analyzer doesn't have a direct readout for efficiency - that would be something to focus on that would have some benefit.
I think as the thread has meandered around we have established that, whether or not this is the worst portable antenna on the market, it has shortcomings, and there are plenty of better alternatives.
Don't shoot the messenger hihi. All is okay by me. resonant mono band dipole with coax works perfect.
You would be better off sticking a long piece of wet spaghetti in your radio than this antenna.
W/o chile sauce it won't work.
