hey, so once upon a time we ran a contest to see if you could identify a location or piece of the tarawa ( really enjoyed learning about the ship). maybe one of you can answer the question.

tarawa had what i would call antennas that would be vertical in port but would be lowered off the bow and looked like down riggers .   im guessing infact these were antennas, but dont antennas work best when vertical ?..    what were they for ? uhf/vhf ?

HAHAHA!!!!!  As the Radioman that had to crank those antenna up and down, I will NOT answer until everyone has a change to answer.  Then I will let you know how they operate  [smile]

Were they lowered to be parallel with the surface of the water? Click image for larger version - Name: image.jpeg, Views: 18, Size: 53.17 KB

Ok, the Flight Deck edge antennas are Omni-directional, so their position up or down, doesn't matter that much.  They were used in the HF 2-30 MHZ range.  On the Starboard side Forward, there are 5 Receive antennas. Starboard side Aft, are 2 Transmit antennas. on the Port side Forward is 1 Transmit and 2 Receive antennas that were connected to Aux Rad (Auxiliary Radio) that is forward of the Aclime Room.

On the 08 Level was our antenna farm with Monopole antennas for HF.  There was also the Birdcage antenna (Dis-cage) for 2-12 MHZ Transmit and a wagonwheel shaped 10-30 MHZ Transmit (Dis-cone) antenna.

On the top of the Aft mast was my favorite antenna, the Rotating Log Periodic Antenna.  It is a beam antenna whereas the RF signal is concentrated in a narrow beam in the direction the skinny part of the antenna is pointing.  It is used for 12-30 MHZ Transmit.

There is also a wire Fan antenna for 2-6 MHZ Transmit that is on the Forward Mast.  We had to make sure nothing was connected to the antenna because it had to be disconnected near the top of the mast so the mast could fold down to fit under the Coronado Bridge.

And now you know.

thanks ... thats what I love about this forum.  it nice to learn about all the systems i lived by and under for 4 years...    i was lucky to be a fresh air snipe. i worked in engine rooms, the well deck( incharge  of the monorail system and napped alot on the ready life boat ...   but other than that..  most of the ship is a mystery...

i knew we had aux steering ( been there) but did not know we had aux radio room..    how many aux /redundant systems did we have?  we also had two bridges right?  were they the same / similar???     cant tell you how bad ive love to get back on that boat and have free access to look around...

There was a room next to Aux Rad called the Panama Canal room which was used to pilot the ship through the canal.  I guess it was a secondary bridge but it would have had limited visibility.  If you look at the bow, there are only 3 (I think) portholes.  The other round things are antennas that went to the SSES space for HF Direction Finding.
