    ANTENNA - DOUBLE BAZOOKA

    The Double Bazooka Dipole is a very efficient single band antenna which is very quiet, and does not require the use of a balun. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends. Do not break the center conductor....

    DELTA MINI SUPER LOOP ANTENNA - WH2T

    Here's how to make the "Super" antenna. To build this antenna you need a lot that is at least 100 feet across. (This can be on a diagonal). Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands This antenna works as a Full Wave Loop on 80 Meters and also works as a 2 wavelength...

    DELTA LOOP INFO

    Full-wave loops are very popular antennas. They are especially useful on 80 and 40 meters where they perform well at modest heights. These are closed loops that are one full wavelength long. Horizontal loops may be fed at any convenient spot. For best performance, make your horizontal loop into a square...

    Home-made 1:1 Balun

    A Home-made 1:1 Balun (for the open half-wave dipole antenna) Going from an 'unbalanced' transmission line...to a 'balanced' antenna, both of which having an impedance of 75 ohms...one needs to construct a 1:1 balun...in order to 'balance' the 'unbalanced' transmission line. This balun will then let...
