My homebrew vertical multiband hf antenna
I have 5 band vertical HF antenna without lossy traps, stubs, loading coils, a 1/4 wave on each band that already survived two small storms
Off Center Feed Dipole all ham-bands 160M-10M
This Off Center Feed Dipole antenna OCDF is used on all ham-bands 160M-10M. I'm using it with my PALSTAR AT1KP
QRO No Tuner Multiband Dipole
One of the last upgrades to the dipole before experimenting with high-power tuning was to change the 300 ohm window line to 600 ohm ladder line. The higher-Z open-wire lines experience less loss overall, which means that they can operate at higher SWR than the lower-Z lines for a given loss value
Rhombic-Math Antenna
Termination resistor needs to be near 800Ω Resistors must be carbon resistance not inductive
