8	How can the voltage at the center of a resonant half wave dipole be zero if the input impedance is 75 ohms?
6	How can I get rid of RFI coming from my house solar panel inverter?
5	Does a loop antenna have less susceptibility to atmospheric noise than an open ended antenna?
3	What is the main source of error for SWR meters?
3	Ham operators often tell me that comparing gain to an isotropic radiator isn't much use because it's only a theoretical antenna, is this true?
