These are the new low-band coils which perform on frequencies to 3.5 mhz. These coils are best utilized for medium DX contacts in a vertical configuration with single-sloping counterpoise. Our counterpoise kit (see drop-down box below) includes 66' of our Teflon-coated, silver-plated copper wire (black colour) wound on a kite line winder with a brass adapter for quick attachment to the VersaTee. In the dipole configuration with 2 coils, it is recommended to add additional length to the antenna to cover all of the 80m band and to increase bandwidth. Our new long telescopic whips accomplish this (see our accessories section).
Because of the high Q of the coils and the short overall length of the dipole antenna for the low bands, bandwidth is minimized. In order to be able to have some tuning flexibility within the band it is recommended to use a small tuner at the transceiver.
In either the vertical (one coil) or dipole (2 coils) configuration it is necessary to use a balun with significant choking impedance to prevent RF feedback. Our TRSB (Triple-Ratio Switch Balun) is an excellent product for these applications (see our accessories section).
Please Note: Coils are not provided with coil clips. Coil clips can be purchased on our accessories page.
