Butternut HF2V Ground Plane antenna Hints + 160mt kit, IC8POF
The HF2 works on 40-80 meter bands and on 160 with an add-on kit
Butternut HF2V 80 and 40 meter modifying
A few years ago, I spent an afternoon modifying my HF2V to improve bandwidth and performance on 80 meters
Butternut HF9V
La Butternut e' stata ottimizzata direttamente sul tetto con ROS prossimo ad 1:1 in tutte le bande tramite analizzatore MFJ alla base
Compact 4-SQUARE 40m Antenna
The cross arms can be oriented to any compass bearing to suit personal needs.2. The four 1/4 antenna wires are cut for the 7MHz band using the formula 1/4 feet =234/F MHz. For 7050 KHz this works out to be about 33' 3" feet (10.19m)
DF Antenna Arrays
Perhaps the most important piece of of the DF array is arguably the antenna itself. For a system that uses an electrically spun antenna like a doppler DF- this is certainly important
