[TowerTalk] My results with the QSO King 125' antenna

[Jim in Waco WB5OXQ]

I just want to let you know how well my antenna works.  I compare it to my other wire antenna a 135' doublet fed with 300 ohm window line intlo a Dentron MT3000A tuner.  The dipole center is 55' and the QSO King fed end is at 50'.  The dipole ends are 20' and the far end of the QSO King is at 30'  The Coax on the QSO runs 50' straight down to the ground and turns right 2' to the outside wall of the house and runs 20' along the ground to a wire spool where about 25' are wrapped around the spool and the remaining 5' go into the shack to the tuner.  There is a 14ga solid insulated wire on the ground terminal straight down beside the coax where there are 450' of insulated radials stapled to the ground in as many directions as possable.  Some are only 25' others are as long as 60'.
Both antennas will tune 160-10 with the Dentron tuner.  The internal tuner in my TS-2000 can only be used with the QSO King because the dipole is 300 ohm.  On some bands 20-15 the QSO King barely needs tuning at all.  I can tune the lower end of 6 meters on the QSO King with the internal tuner.  6 meters is outside the tuning range of the Dentron tuner.
Performance is in most bands pretty equal both transmitting and receiving.  Sometines ther dipole is very slightly better but others the QSO is better but neither wins by much.  On a nightly 75 meter net I work stations in many states from my Central Texas home mostly using the QSO King and run a killowat and get 40 over s9 reports from nearly all stations.  The QSO King antenna can be used in all weather but the dipole can not be used when windy conditions blow the feedline against the support tower and the swr fluctuats too much.  Over all I am very pleased with the antenna.  Jim WB5OXQ
