^ ... I just need a base antenna ...

Start out by making a multi-element dipole antenna cut the legs of the dipole
according to the discussion in this group on vertical dipoles one pair for
each band that you want to listen to solder one end of one leg from each pair
together then solder those to the coax the final product will appear similar
to cat whiskers if you have any questions just ask here after you have used
this inexpensive antenna for a while you will know if you need to spend more
money on an expensive one
