 Posted: Mon Nov 17, 2008 11:34 pm Post subject: 406 MHz ELT and RV8 |
 |
|
I changed the subject because I feel that there is a definite issue as to ELT mounting on RV8s as Skylor mentioned.
The canopy slides back all the way against the vertical stabilizer fairing – so that leaves no room on the back deck. On the premise that the antenna must be vertical, this leaves the following areas on the outside:
<![if !supportLists]>· <![endif]>On top of the vertical stabilizer
<![if !supportLists]>· <![endif]>Forward of the wind shield
<![if !supportLists]>· <![endif]>On top of one of the wings – certainly feasible but so ugly!!!
<![if !supportLists]>· <![endif]>On the rear of the canopy fairing – ground plane issue ? Furthermore would require that the antenna cable move back and forth with the canopy.
Inside of the cockpit would seem to be a bad compromise as it would not be vertical and would be close to metal, hence serious concerns as to its transmission capabilities.
As to mounting it under the vertical stabilizer, horizontally, probably a bad compromise as the antenna is horizontal and masked by a fair amount of metal.
Then there is another issue. If the plane tips over during the crash, then all the topside locations are rendered useless.
Question : Is it OK to place two antennas on one line via a splitter or are splitters good only for receiving antennas such as VOR + ILS. If that were the case, then it would be possible to have two ELT antennas, one on top and one on the belly. The down side would be that if the belly antenna were zapped during the crash, it might ground the cable and render the top antenna useless.
Any thoughts ?

Objet : Re: 406 MHz ELT
All of this discussion regarding mounting of the ELT antenna is very interesting and eye opening, but we -8 builders have one issue: There is simply no place on top of the fuselage to mount the antenna because the canopy on the -8 slides all they way back to the vertical stabilizer when it's open! As far as I can tell, this leaves only the options of mounting the antenna in the cockpit, or underneath the empennage fairing as others have done. Anyone have any other suggestions?

When I was flying missions with Civil Air Patrol in the State of Oregon we
had far more 121.5 ELT false alarms than real activations but...we responded
to every one of them and learned some lessons along the way. Most of the
missions I was associated with were production spam cans who had their
antennas mounted on top of the fuselage behind the cockpit. Yes it's ugly
but they put them there for a reason. When the ELT IS activated in a crash,
these installations have the BEST chance of being located by search and
rescue (SAR).
Scott's waveguide premise is correct, the cockpit does make a great one and
NO that is not helpful in getting one located and rescued in a timely
manner. If you land (crash) right side up that waveguide will direct the ELT
signal upward where the satellites will receive it. But, once the 121.5 ELT
is heard by the satellite and a SAR aircraft dispatched, the area to be
searched is still quite large. The SAR aircraft has to be able to
"hear" the
ELT in order to pinpoint you. If your installation is in the cockpit then
this waveguide effect means that the SAR aircraft's direction finding (DF)
equipment needs to be A LOT closer to you to pick up the signal. That takes
more time in the grid and eats up precious time getting help to a stricken
pilot who may be badly injured.
This waveguide effect was brought home to me quite vividly on one CAP
practice mission where our incident commander placed the ELT inside a metal
garbage can and then tipped the can on its side with the open end facing a
mountain peak. We spent hours with the direction finder pointed at the
mountain listening to the reflected signal from the garbage can waveguide
and searched all over that mountain but never located the "stricken"
aircraft. A frustrating exercise but very eye opening.
John is correct, the practical value of "hiding" the ELT antenna
along the

Since 406 MHz ELTs still use radio waves to perform their magic, everything
I just mentioned applies. There will be a lot fewer false alarms on the 406
ELTs IF AND ONLY IF all you aviators out there fill out your registration
cards and mail them in. Then, when the USAF search and rescue center gets
your signal they can phone you right away and find out whether it's just a
false alarm or a real emergency. The good news is, if it's a real
emergency
the satellites will pick up your 406 MHz signal quicker and locate you
within a smaller radius of area. The only down side is for the SAR team,
the 406 ELTs send out a burst of data every so often as opposed to the
continuous transmission of the 121.5 units. This makes DF tracking a little
more difficult but you should still be found much more quickly than before.
Recommendation: read the instructions that come with your unit and mount the
antenna where they say to do so. If no instruction, mount on top of the wing
or fuselage in an open area with the least potential for reflections. And
PLEASE PLEASE register your unit. I live ELT

John is correct, the practical value of "hiding" the ELT antenna
along the
roll bar or under the tail fairing is ZILCH!!! I just finished my RV-6A and
mounted the ELT antenna on the top of the fuselage behind the sliding
canopy. Yup it's ugly sticking up there but...if I do go down and the unit
is activated, that location gives me the best chance of being found as fast
as possible. Yes I know the activation rate is not that great but...you
spent good money on and are installing a tool that could save your life in
an emergency so why not give yourself the best chance of having it do some
good.
Since 406 MHz ELTs still use radio waves to perform their magic, everything
I just mentioned applies. There will be a lot fewer false alarms on the 406
ELTs IF AND ONLY IF |

the 406 ELTs send out a burst of data every so often as opposed to the
continuous transmission of the 121.5 units. This makes DF tracking a little
more difficult but you should still be found much more quickly than before.
Recommendation: read the instructions that come with your unit and mount the
antenna where they say to do so. If no instruction, mount on top of the wing
or fuselage in an open area with the least potential for reflections. And
PLEASE PLEASE register your unit. I live |

the satellites will pick up your 406 MHz signal quicker and locate you

I think you can put it on top off center-line just aft of the sliding canopy?

I changed the subject because I feel that there is a definite issue as
to ELT mounting on RV8s as Skylor mentioned.
The canopy slides back all the way against the vertical stabilizer
fairing ' so that leaves no room on the back deck.
