Who Sparks on short distance will not be bad. But who expected miracles from a 5 cm dummy load, did not understand the technology. What 5cm antenna has a radiation power if the ratio 1/4 wavelength to mechanical dimensions 0.6 at 70 cm, at 2m even 0.07. Since nothing can go, except the transmitter vorgaukeln 50 ohms, that he is satisfied. By the way is probably a big 2 watt resistor type coal with low L the same in effect.
Did the part goes to 70 cm at close range with 1 Watt crow 8 km to the Repeater extent. 2m is simply nothing except heat in the coil when more power is the thing ne heating. Radio FM is available even at close range local station or something. Positive at small spark is precisely the thing fits into your pocket incl Funke (see UV3r) Therefore useful, but not a miracle.
