[Towertalk] Re: 15M on C31XR

[N6ZO@aol.com]

With due respect, I do not think you understood that post correctly.

Lets not take force 12 to task for this problem  The owner has stated that he
made unauthorized mods and he said he only had a "feeling" things were not 
quite what they could be.  For contesting, I think it was N4KW who pointed 
out that
90 feet might be too high for 15 meters at certain times of the day.  This is 
consistent with what I have seen with stacked beams on 15 where the lower 
beam in the stack at 45-60 feet is better than the higher "identical" 
antenna. This is especially true when running the EU guys on 15 in the 
afternoon. I have a c31xr that worked fine right out of the box. Did I have 
some problems with  "tuning" but they all turned out to be from interference 
from BC stations affecting  my MFJ analyzer.  Not the antenna.   On the other 
hand, the "MANUAL" for this antenna could use a little beefing up.

The answer here may simply be to get a hazer or a crank up tower and lower 
the antenna as conditions dictate

I shared my views with the owner privately.  In one sense I hope you don't buy
one,  I don't need the competition.

I have had a TH6, a TH7 and a 4 el 20 hygain at this QTH.  My c3` antenna 
went up after a contractor working in my back yard knocked the tower over.  
If that were to happen again I'd have another order off to Force 12 for 
another one tomorrow.
