Choosing a Ham Radio - American Radio Relay League
www.arrl.orgmodels. You’ll need two types of antenna; a dual-band quarter-wave mobile whip antenna for 2 meters and 70 cm (there are also tri-band antennas that include 6 meters), and a mobile HF antenna. A permanent or magnetic mount with one or more interchangeable single-band HF whip antenna is a good way to try operating from your vehicle.
A 9:1 Balun For Your End Fed Antenna - Mobileers
www.mobileers.comJan 09, 2013 · Transformer coupling and properly grounding your end-fed antenna will offer you four benefits: (1) Greater signal levels across a larger bandwidth (impedance smoothing), (2) Less electrical noise pickup from local sources (common mode rejection), (3) Greater protection to your equipment (constant static bleed and near-strike (DC only) shunting

A six-band, HF Windom antenna - QSL.net
www.qsl.netA six-band, HF Windom antenna April, 1997 This Windom antenna was marketed in the late 70's and early 80's as Smithe's Windom. It was designed to cover 80, 40, 20 15, and 10 meters. By serendipity, it also covers the 17 and 2 meter bands. Now, how was a Windom antenna developed? It began with a center-fed, half-wave dipole.
Antenna Height and Communications Effectiveness
www.arrl.orgplanning board to want to restrict antenna installations to low heights. However, such height restrictions often prove very counterproductive and frustrating to all parties involved. If an amateur is restricted to low antenna heights, say 35 feet, he will suffer from poor transmission of his own signals as well as poor reception of distant signals.
