Regarding the Manteca Magnum:
I can adjust the freq of the antenna by shortening/raising the length of the vertical radiator.
By placing taps, you lose the PRECISE match. (Taps are great for beginners to search around for freq, or people who are not running a 24×7 operation, by the way)
By using the white pvc, you screw up the inductance SLIGHTLY.
This is a very precise antenna.
RE: The sstran antenna – this is GRAT for people who are experimenting with different freqs, or dont care about getting that last little bit out of the rig. For me, getting it dead on as close as possible was more important than freq hopping.
[quote:43ba36739d]None of the currently available transmitters have any sort of circuit that will compensate for a mistuned base-loaded part 15 compliant antenna. [/quote:43ba36739d]
Some day, we’ll have to show you the manteca transmitter design. 🙂 .
Also – please folks, keep an open mind – 3 years ago, people were claimng that the tesla antenna could not possibly work… now, most of us are using them. FINITE CERTAINTY is almost always dis-proven..
