Dear Topbanders, I am planning my next move with the beverages and I would like to hear your opinions about 2 areas.
Looking at the pattern response for beverages in for example ON4UN book, I found that If I install 4 x 600 feet or 5 x 900 feet beverages, I should cover 360 degress with deeps of no more than 3 or 4 db respect the main lobe. Taking into account that most people will not work extra without any benefit my first question is: 1 - Why many DXers and contester install 10 or 12 direction beverages ?? What am I seriously missing with my simple analysis? 2 - Is there a meaninfull or simple way to determine if at my location is worth to go from 600 to 900 feet? I did some measurements a) I injected a signal into the beverage and using a current probe, I meassure signal strength in an Smeter.(I replaced the mA with the input of a transceive) Variation was about 10db from begining to end of 900 feet. Curiously the 600 feet one gave aprox same result but I recognize S meter granularity was not good. b) I disconnected termination resistance and the signal stregth with or without it was 8db. 900 feet Bev gives about 20db F/B in broacast band Many thanks in advance to all _______________________________________________ Topband reflector - [email protected]
