[MRCA] Memorial Day antenna

Tue Mar 27 08:52:09 EDT 2018

Hello Tim,
         I never thought about doing a bamboo pole.  That's a thought.  I'm also now looking for that pole gizmo the Signal Corps used to string wire.  I might not be able to find an original, but if I can see a picture of it, I might be able to make one.  Of particular interest would be what diameter of the pole - for strength.  Of course, plans for anything I come up with I share with the MCRA.

         My original thought was using a stair rail and attaching a pulley on the top, kind of like a flagpole. That may not have been too far off from this Signal Corps pole. 

         Of course, if anybody in the MRCA has a picture or knows the nomenclature of the pole the Signal Corps used to string wire, that would be helpful.

Hi- I get them at the outdoor  / gardening store.  Ours has various sizes and lengths.  I have also gotten them at carpet stores - sometimes carpet stock arrives rolled up on a bamboo pole..

If you are "doing" a Pacific theme, presto.  Bamboo also grows in southern Europe in case someone challenges your authenticity...haha.  I always have a few long pieces with a wire hook on the end - perfect for stringing wires thru trees, grabbing throw weights, hanging loops on elevated structures.  Essential actually... 

The Signal Corps also had a 2 piece wood pole with a hook/pulley gizmo that was used to string elevated telephone wire.  I forget the nomenclature but that would be authentic too if you can find one... 

Have fun!

I never thought of bamboo. That would work. Now I just have to find pieces long enough and thick enough. Thanks.

 I usually carry a few pieces of bamboo for that sort of situation.  "Improvise, adapt, overcome".  It surely was used operationally!  A short piece of black rubber vacuum hose for insulation at the radio end of the wire would keep everyone happy.  An SCR-284 can produce a considerable burn...especially when driving a halfwave wire.

Here ‘ a question for the group. I’ll be using an AN-101 ( long wire antenna, issued as part of the BC-1306 radio set) long wire antenna in an Inverted L configuration with the BC-654 radio.  I have a tree to tie off the far end to. What I need is a non-conducting pole close to or attached to the WC-52 that keeps the wire antenna in the air until it reaches the truck, and also allows me to run the antenna into the radio, mounted just behind the assistant driver’s seat in the cargo bed, without the wire touching anything before the connection to the radio. My questions are thus 1) was there any issue pole that did this, or did GIs just use what they could find, and 2) would running the wire inside a three foot section of rubber hose as the wire comes close to the vehicle effect transmission/ receptionist adversely.

 Being that the set up is being done at a display at the Franklin D. Roosevelt Home and Presidential Library in Hyde Park, NY, doing some cobbed up job of putting up an antenna is out of the question.  Fiberglass cammo net poles are out, since they weren’t yet in existence before 1945. I was thinking of using a wooden staircase bannister as a “flagpole” to do the job. Before I do that, though, I wanted to see if anybody knew of some official, issued pole that did the job.

 The instructions for the AN-101 antenna specially say not the let the antenna touch anything like tree branches when stringing the antenna that would grounding it.  I want to use the section of hose, which would certainly have been available in 1945, to keep anything or anybody from coming in contact with the wire antenna near the vehicle.  The only place I should have to worry about that is the area close to the truck where the radio is mounted in the vehicle.
