[TowerTalk] Mosley S-402

[Billy Cox]

In this case John, it is necessary as I believe that model uses center loaded 
elements there at the boom to element mount, so he will need to follow Stan's 
and your advice advice and and locate something a bit more robust perhaps. 

Hope this helps!

I have no personal experience with Mosley. It is not necessary to insulate 
the parasitic elements however doing so makes calculating the lengths much 
easier as there is no boom/bracket compensation. Also the boom resonance 
is easier to calculate should you have multiple antennas in various 
directions. Direct mounting will likely require some tip length changes. 
You can purchase insulating material at McMaster Carr and other places 
should you wish to fabricate new heavier duty insulators or you can use 
Stauff clamps or possibly DX Engineering element brackets.

For the second time I've had a broken element support issue. The first 
time a F1 tornado came through and I lost half of the reflector. A few 
weeks ago, a 45 mph wind gust took off half of the driven element. Those 
insulator blocks have failed each time right at the coil to element 
connections. 

Does anyone know where I can get ideas as to how to bag the little blocks 
and still have the elements insulated from the boom? Also, I see that my 
Mosley CL-33 doesn't have the director and reflector insulated from the 
boom. I thought that if the driven element was insulated from the boom, 
all elements had to be the same. 

Thanks.
