[K3PZN-List] bozooka antenna verse diapole antenna

I presume you might be asking about 80m?  


For 40m, a dipole generally covers the whole band.  Note the percentage:  300/7000 = 4.3%

In contrast for 80m its 500/4000 = 12.5% -- as a result a dipole using has a 'match' over a smaller part of the band.  Hence the interest in the Bazooka antenna.  


I confess to not having a coax fed dipole for 80m, but in this modern age I suspect a dipole with decent coax and a decent tuner in shack should work fine - particularly in this age of auto tuners.  If the dipole has its resonance near the middle of the band, it might be ok.  


I can't remember if one of your wire antennas is ladder line fed?  If so the bazooka has no advantage over it - because ladder line is even lower loss than coax.

On the higher bands - greatly mismatched coax has a more dramatic effect -- the multiple bounces combined with higher coax loss equal greatly reduced power.  As a principle, coax is best used with matched antennas - but on 80 and 160m one can get away with some mismatch.  Usually the first problem down there is RF into the microphone.  


I sense bazooka antennas were much more popular before auto tuners - to minimize labor in operating a station on 80m.  They tend to be expensive and heavy as they are made of coax - so I suggest sticking with a dipole.  


I wonder what others think on this?
