[TowerTalk] TH6DXX matching/beta tubes question

[Tom_N2SR]

Hello All!  


I have a TH6DXX that I will be refurbishing soon (and it will be for sale after that).   

I know there are several versions of this antenna.  Mine has the standard beta tubes
which terminate into a loop of aluminum wire approximately 12 inches long, which is 

then grounded to the boom.  


My question is, could I purchase longer beta tubes, cut them so they would match the 

length of the current beta tubes + aluminum wire, and then use the same type of beta 

tube grounding mechanism that is used on the TH7DX antenna?  

Would that change the feedpoint impedance?  


Thanks!

Tom, N2SR
