Use ONLY silver plated connectors!
Internet and a lot of stores are full of Chinese crap connectors, make sure you buy well branded connectors.
Use a 40 or 45W soldering iron with temperature regulated to 340 degrees Celcius.
Use 60/40 solder.
UHF connector (PL-258) is acceptable ONLY up to 30MHz due to high losses and it doesn’t maintain the 50 Ohm impedance above 8MHz.
Above 30MHz or always if you can, use Type-N connectors.
Last note: coaxial cable RG-58 IS NOT suitable for transmission!!!
