Reviewed by Bob Allison, WB1GCMAssistant Laboratory [email protected] How To Build A 10 Meter Dipole. 160m ocf dipole. Please note that these resonators require a mobile mast (MO-1/2/3/4) and mount which are all sold separately. HF Antennas for Beginners – 30 Meters and Below Gary Wescom – N0GW January 2, 2007 For a ham who is new to HF operation, there is a number of new things to learn. Line Isolation / Choke Balun: A line isolation balun isolates the antenna elements from the coaxial transmission line so that power is radiated by the dipole antenna elements and not by the feed. K6IF/W6BDN 40 Meter Rotatable Dipole. Mine are for 40M. It works good on 80-15 meters. Hanson, KJ5VW Austin, Texas Imitation, it is said, is the sincerest form of flattery so let me begin by pointing to the direct source of my inspiration for building this antenna. Hamstick dipoles Isolate one for each band 80 mtr pair Could be any band Must be in pairs Best to tune-up on a vehicle Could be mounted in attic Or in back yard out of sight Coax to station 40 mtr pair. MFJ Short Mobile HF Whip Antennas are designed to let you mount an HF antenna with just a 5 in. My lot is only 9 meters wide and around 13 meters length is available for antennas and wires (behind the house).
