Hi Have some second hand connectors to suit LDF5-50 and LDF4-50 and LDF2-50 or their RFS equivalent.
$5 each.
These connectors are solderless, all you need is a set of spanners (and a good stanley knife) to terminate the coax.
I also have a good range of RG214 jumper cables with N type connectors on them. $1 each.
And some short runs of heliax.
