G5RV Multi-Band Antenna
The G5RV antenna , with its special feeder arrangement, is a multiband centre-fed antenna capable of very efficient operation on all hf bands from 3.5 to 28mhz

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
Random wire unun for multiband built in autotuners
The UNUN. It is quite easy to do and allows you to use a 23 'wire antenna and a 23' counterpoint and get full coverage from 10 to 40 meters
