Ladder Line | KV5R.COM
2015年7月5日 · The 1/2-wave 80-meter doublet with ladder line all the way to a 1:1 bifilar choke/balun in or near the tuner is a much better antenna for 80-10, provided you adjust the …
The All Band HF Doublet - 80 thru 10 Meter Ladder Line Multiband Antenna
The all band doublet antenna is nothing more than a 1/2 wave dipole cut for your lowest operating frequency and fed with twinlead, ladder line, open wire, etc to a tuner that will accept a …
80-Meter Doublet | KV5R.COM
The general rule for “good” ladder line lengths is odd-eighth-wave, i.e., 123/f=feet, x1,3,5,7,9 etc. (where f is MHz of the antenna’s fundamental resonance). Even then, some pruning may be …
