Buddipole reel for 80m
These are the new coils for low bands that work up to 3.5 mhz.
These coils are best used for medium-distance contacts in vertical configuration with a single sloop counterweight. A counterweight of about 20m is recommended.
In the dipole configuration with two coils it is recommended to add length to the antenna to cover the entire 80m band. and increase the bandwidth. Our long telescopic whip achieves this goal.
Due to the high Q of the coils and the short total length of the antenna, the bandwidth is minimized. To get more flexibility it is advisable to use a tuner.
In the case of the vertical (a coil) or the dipole (2 coils) it is necessary to use a balun with a significant preventing rf re-entry. Our TRSB (Triple-Ratio Switch Balun) is suitable for this application.
