• 40m loaded dipole - This is an short dipole for 7 MHz. Total length of this dipole is just 10 meters, 33 feet. Missing lenght is balanced by a coil made of 49 turns of a 40mm diameter pvc pipe. The use of a choke balun is recommended, as always, to adapt the unbalanced coax cable to the balanced antenna, and to prevent RF feed back along the coax shield.

• Coil-loaded 40/80 Meter Inverted V Dipole Antenna - An inverted V antenna for 40-80 with loading coils. This antenna is a full size on 40 and a shortened 80 by KG0ZZ.

• 80m Shortened Dipole Antenna - This antenna just requires about 24m of free space instead of 41m that a normal half wave 80m antenna needs to hang up. The so called loaded dipole uses a coil in every dipole arm to electrically lengthen the mechanical too short dipole arms. Every coil has an inductivity of 120 microHenry.

• Short Multiband Dipole Array - A multiband shortened fan dipole. This page offers and online calculator that can be really useful if you plan to homebrew a multiband dipole for low HF bands and you don't have all needed space for the full lenght. It combines multiband dipole with loading coild for selected bands.
