My 80 meter bent half square was probably the best antenna I ever had. I had it broadside to Europe at my Hampton Va QTH, I had it broadside to the Pacific area for one contest at my New Kent location and then installed it again broadside to Europe.
Very hard to work Europe off the ends so I took about 5 hours to rotate it. Only rotated it once! It is important to note that a half square is not worth the trouble on 20 meters and above because a dipole at the same height as the top wire of the half square has more gain for DX.
On 40 meters the top wire is about 35 or 40 feet and a 40 meter dipole at that height is about the same as the half square and a dipole is easier to put up.
Thanks to Mani for finding this Video.
Hi All.
A very interesting and informative video, however, the continuos use of DBi I think deserves explanation. Please note accuracy.
Cheers. Roy.
Difference between dB and dBi
Factor
Antenna gain measured in dB
Antenna gain measured in dBi
Purpose
dB is to measure the relative strength of a signal
dBi is to measure the gain of an antenna
Standard
dB is used as a standard unit of measurement in many industries
dBi is specific to the field of antenna design
Calculation
dB is calculated using a logarithmic scale
dBi is calculated using an absolute scale
Reference
dB is a relative measure, with respect to a reference point
dBi is an absolute measure, relative to an isotropic antenna
Directionality
dB…
Thanks Craig. Thanks Mani
very good presentation
