Ron- 

Mine is on the bottom of the port access panel in the baggage bay.  I ran irrigation tubing through the wings containing #18 wire for both the strobes and position lights.  I did not want to mount something that weighed as much as the strobe controller in the wing.  I have seen a few mounted directly to the spar with an access panel in the wing skin.  I did not want to put another panel in the wing.  The answer for you might be to use very light weight coaxial cable for the strobe portion with the shields well grounded and your controllers located on the port and starboard baggage bay access panels.

Hi Ron,



I put a single strobe power supply on the outboard end of each spar with

an access hole below.

The strobes will be uncoordinated, but I keep the high voltage wires short.

Attached some pictures, quality soso.



Access holes are a little large, because my first plan was putting the

power supplies on the lids.

Power supply attachment using reduxed McMaster-Carr studs and bid.

Light fixtures attached with cut down studs reduxed only.



Regards,

Jan de Jong

Hi Ron,



The other 3 pictures I thought to send.

Ron,



FWIW... Absolutely no noise problems with my Whelen strobe power supply (mounted on the baggage bay bulkhead below "D" door).  Power supply is grounded.  Strobe HV lines have shields grounded at the power supply end and strobe shields are connected through any connector in the link.

Also, I have the LED/Strobe heads on the Europa.  The LEDs are VERY bright!  Much brighter than standard incandescent lamps.  Everyone who has seen the Nav lights on the aircraft in the air has commented on how bright they are.

Now I have a set of Nav/Strobe heads with incandescent lamps that I'll never use.  Was going to put them on my Toot but have changed my mind.  From now on, only LED units go on my aircraft!  

Check six,

That's exactly what I did, beautiful installation of my Kuntzleman power supply on the starboard baggage bay rib.  When I tested, if there is an antenna cable (RG-400 or RG-142), radio or antenna within 8 feet of power supply, tick, tick, tick. Nothing I tried helps. Power supply is grounded. Supply lines are shielded, I tried no ground, ground on supply side and ground on power supply side. I tried wrapping power supply in 2 layers of aluminium foil figuring RFI leaking out of connectors, no joy grounded or un grounded. I tried wrapping antenna cable with aluminium foil, grounded and un grounded. i tried grounding antenna cable. Nothing works, have to turn squelch up where don't get what it is I want. 



The only thing that helps is moving power supply at least 8 feet away. I hear from a local IA that Whelen is the only powers supply he uses because he had noise issues with others.



Kunzleman power supply is pretty small, 10 oz and each one uses ~ 1.5 amps. I have their combo LED/strobe heads already mounted.



When you test yours, let us know if you have good results.



My experience is pretty much identical to this builder:

Bob,



What is your set up for your antenna(s)?

Fred,



I have a Bob Archer Model 6 big E antenna in the tail with the coax  

running forward to the center seam then down the fuselage port side   

seam thence following the fuselage seam to the firewall.



I have an AAE VHF-5T mounted vertically on the port side window frame  

down to the floor with the connector at the fuselage seam and the coax  

running along the seam forward to the firewall.



I have two Bob Archer Model 7 "V" antennas for VHF Nav.



One mounted on the bottom of the fuselage aft of the baggage bay with  

the coax running down the center line to the front of the lower  

baggage bay where it turns port and runs up the fuselage to the seam  

and then forward to the firewall.



The second is in the area over the baggage bay with the coax running  

forward to the back door frame where it turns port and down to the  

fuselage seam then forward to the firewall.



Finally, I have a Bob Archer Model 5 Transponder antenna mounted on  

the port side of the balance arm containment with the coax running  

down to the bottom and up the side of the fuselage to the seam and  

forward to the firewall.



All the antenna coax run down the port side fuselage seam  All  

electrical stuff runs down the starboard side fuselage seam.  Not sure  

all that is necessary, but it doesn't hurt either.



I have not had the opportunity to work with the VORs yet so I can't  

say how that antenna arrangement works for sure.



I hope that helps.

Bob...thanks for all this info...sounds like an exquisite  

installation...I have a couple questions, inserted and indented below.

	I take it the coax is on the centerline of the "roof" (not the floor)  

of the fuselage.

	Why two?...Are you running dual Navs? Are you IFR equipped?



	(Note: The Aviator's Guide to GPS sez the FAA's phase-out of the  

whole VOR/DME network is 				expected to be complete by 2010...or has  

that been postponed?)

	Is this antenna superimposed over the coax from the Big E?

Hi Ron,



Don't even have an antenna yet so no results and still counting on luck.

 From your link it would appear that the Kunzleman switching power 

supply radiates some at radio frequencies.

You probably should determine whether that is your problem too.

Separation will help, orientation may help.

Jan de Jong

Dear Europaphiles,



I know that this may be a little late for those of you who have already 

bought their strobe power units, but my installation works well without 

any interference. I have Whelen equipment and I mounted an HTS power 

supply at each wing tip. They are mounted on removable panels on the 

bottom surface. There is a weight penalty of about 1 pound compared to a 

single HDA power supply in the fuselage but all the high voltage cables 

are short and at the tip. No problems.



Cheers, John
