[Milsurplus] Need TCS antenna advice

[WA5CAB at cs.com]

You don't normally try to end feed a half-wavelength antenna.  It's aq hi-Z 
point.  Aboard ship (on at least three amphibs and two cans I served on, the 
normal antenna for the TCS was around 45-60 feet long, including the feed wire 
inside the compartment.  And it was end fed.  The outut circuit of the TCS is 
similar to that of the HF Command Sets, and was designed to feed a relatively 
short unbalanced antenna, not a doubloet or dipole.  It will work well, 
however, with a Windom.

I have several antenna loading coil units.  But 
I'm also in the midst of a major computer failure (I'm on the laptop with the 
miserable keyboard)  When I get the main machine back up I can maybe check 
whether one of them is marked for TCS-8 or not.  However, as Breck indicated, my 
TCS-14 loads a 50' endfed wire with the ATU switched to zero, using only the 
internal loading coil.
