With today’s postage-stamp-sized lots, some hams can only dream of installing a dipole for 80 meters — or even 40 meters. The most common solution has been to add loading coils to reduce length. The Alpha Delta DX-DD , for instance, offers 40/80m coverage in half the space of a typical dipole. Loading coils work, but it comes at the ...
