A Co-ax Trap Dipole For 40, 30 and 20 Meters
- Another way to minimise the loss of an antenna using coax traps is to use the minimum length of coax needed to achieve resonance

My homebrew vertical multiband hf antenna
Off Center Feed Dipole all ham-bands 160M-10M
QRO No Tuner Multiband Dipole
Rhombic-Math Antenna
160
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
