Anybody here use the tiny-tenna? Is it any good? Arky Bob, Build your own 1-Transistor Active Antenna http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=7550 http://www.ee.washington.edu/circuit...activeant.html http://circuitdiagram.net/active-radio-antenna.html TIP - Mount the Whip {Antenna Element} and Amplifier outside a Window at 45* like a Flag Pole. Coax Cable to Radio with Speaker Wire for power leads to a Switch & Battery near the SWL Radio. Better a make your own 2-Transistor Active Antenna http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=22731 http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=16539 http://www.qrp.pops.net/probe1.asp Fancier "Tuned Active Antenna for 5 to 22 MHz http://www.hard-core-dx.com/nordicdx.../swactive.html SWL -Newbies- Beyond the "Tiny-Tenna" * DIY- Active Antenna Kits and a lot more . . . http://groups.google.com/group/rec.r...d90a539eb30f90 TSE - Instead of a Short (18"~39"} Whip Antenna Use a Mini 12"16" Hula-Hoop as a Frame for a piece of 300 Ohm Twin-Lead [TL] taped all the way around it. On one end {left-side} use one wire of the TL going CW, and on the other end {right-side} use the other wire of the TL going CCW. This gives you two parallel wires that are equal and opposite that act as a circular-dipole. This Mini-Loop-Dipole Antenna Element can then be both 'rotated' and 'positioned' to reduce your local noise pick-up. hope this helps a 'tiny-tenna' itty-bitty - iane ~ RHF |
