Posted: Sun Mar 12, 2006 8:27 am Post subject: fixed ELT antenna location on Series 6?

I'm trying to find a good spot for the fixed external ELT antenna for my 

Ameriking

AK-450 but I can't seem to find a spot that satisfies all the constraints 

listed in the

manual. On the series 6, the two antenna mounting plates on the top of the 

fuselage

are 26" apart but the ELT manual says that it needs to be 36" from any 

vertically

polarized comm antenna.  What have others done?



I'm thinking I might have to compromise on the 36" antenna spacing and put 

the

ELT antenna at the mounting plate at the back edge of the turtle deck so 

that I

can mount the ELT unit behind the seats where it can be very rigidly 

attached and

the antenna run can be short.



Thanks!

On a tube a fabric plane just zip tie the antenna inside the fuselage 

behind the cargo area. I have my antenna pointed straight back, which 

will probably be straight up in a wreck. Use plastic tubing to make sure 

it does not ground to the tubing. The reason you do this is in a wreck 

you do not know which way will be up, and chances are that you might 

just stick the antenna in the mud and it will not transmit well. If it 

is protected by the aircraft frame it will always transmit well enough 

to get picked up by the satellite and by the rescue crew. If you are 

upright and can get around You can use the mobile antenna and the voice 

transmit feature. I know people will say the book says, outside fixed, 

vertical, and all, but In all the wrecks I have seen that is the worst 

place for it to survive a still transmit.

Scooby,  I did as Alan did - almost.  I made a little bracket that mounts to 

the convergence of the frame tubing just aft of the seat on the passenger 

side and mounted the antenna internally up-side-down.  With a little length 

of rib lacing cord tying the end to the lower frame to keep it from whipping 

around.   I like the internal protection Alan describes, but expect the 

signal to be somewhat less, being inside the frame.  Like Alan, I feel a 

possibly weaker predictable signal to be better than a strong signal stuck 

in the ground by an inverted airplane.

I have my ELT antenna in the frame behind the seat.  I got a call at 1:30 AM 

last Sunday from the Half Moon Bay Police Dept.  I had my airplane tied down 

at the airport and the wind was so strong it set off my elt.  So it does 

work inside the aircraft.  Clint
