I haven't seen much discussion about the location for glideslope antennas and I'm going to need to make that decision sometime soon.



What seems to be the standard choice for antenna type and placement?   Also what type of results are you seeing?

 

Thanks,

Phil

That sounds pretty easy.  Maybe that's why I never heard any discussion about it.

I used the Bob Archer VOR wingtip antenna and the splitter mentioned below.  Works great.

As you are seeing, although it is possible to have a separate GS antenna (ever been in a Cessna with the bow tie antenna on the windscreen?) most people are using a VOR antenna with a splitter. If you have an SL30 it isn't even an option - it has a splitter built in for the GS, and the only input is for a VOR antenna. 

I too use the Archer wingtip antenna, and it works great. It may have a directionally-dependent slightly reduced range for VORs, but I have heard no complaints about it when used for the localizer or GS.

There will be a bunch of combinations and personal  opinions but just for reference I installed the Bob Archer in my wingtip for Nav  2 (SL30).  My 430W is my NAV1 with the CI-157P on the vertical  stab and it uses the diplexer.  At 7000 feet I was averaging  around 30-40 miles better reception on the cat whiskers than the Bob  Archer.

As the above post mentions, you will hear varying opinions on the Archer antenna. I think this is because it is somewhat installation dependent. However, I have not yet heard any negative comments about localizer or GS reception.

My data point: I did not follow Archer's instructions to the letter. From 7000' I routinely receive useable VOR signals (SL30) from 80 miles away - essentially line of sight to the horizon - except when the VOR is 90 degrees to the right, and the antenna has to "look" thru the fuselage. Then range is perhaps 40 miles.

This might be a stupid question, but if you are using a wingtip Bob Archer antenna for GS/LOC, would your position be offset by the 15' or so that the antenna is out from the centerline of the plane?



 Is this something that you can compensate for in the NAV radio?

No worries, Ed, all you do is fly 15' over to the left or right

a little.   You go try flying the approach to 15' lateral

accuracy and let me know when you've got it perfected. 

(sorry, couldn't resist...especially since it was you)

I have an Archer style antenna (we mad ours) in both wing tips so I can flip between the two to get perfectly centered. .



I just got my 200 Hp IO-360 to run LOP and got 152 KTAS at 5.8 GPH with a little tail wind I was getting 32 MPG. Yahoo!

Ed is correct.

I put the antenna in the left wing tip so I am 15' to the right of the approach lights, making them easier to see out my (left) window!! -

Good point, Tim. I had a hard enough time keeping your plane in the HITS boxes!

I used the Comant that others have noted and it is mounted under the horizontal stab on the bottom of the tailcone. I have a splitter installed so that I can use it for the VOR/ILS/GS on both my SL-30 and my 430W. Works great. I can receive vor's on the SL-30 at 90 to 100 nm and usually about 60 nm on the 430W. ILS and GS reception is excellent on both.

Me too.  The Archer is shared by a G430 and SL30.  Works fine.  Only use 

it for practice - in actual I'm 100% GPS.



I used an Archer for my Com2.  I don't recommend doing that.  When my 

Com1 went intermittent (probably from an electrical storm) I found my 

Com2 didn't work well enough to function as my primary Com. Since this 

happened 3 legs from home, I had to swap antennas so my remaining com 

was using a Comant whip.   (Thanks again Kelly!)



The archer Com antenna is gone and a 2nd whip is now on my belly.



I went back and verified that the Archer Nav antenna performed well 

enough approach work - it did.  VOR reception varied side to side per 

the findings by other posters.



I did follow the Archer installation instructions to a "T".  The Com 

works, just not good enough for a primary radio.  And I learned that if 

it won't do primary, then it really isn't a full backup.

I just got my panel in from Aerotronics last Friday and hadn't had a chance to dig through it closely yet.  Once I got home tonight, I looked a little more closely at the GTN750 and SL30.



Viola, there it was.  The splitter is already in place and connected to both radios.  Now I just have to connect the coax from the cat whiskers and I'm done.  What started off as a minor head scratcher turned into a remarkably simple issue.

 

Thanks everyone for pointing me in the right direction.



By the way, the panel looks even better in person than it does in pictures.  It exceeded my expectations by a long shot.  Can't wait to put electrons into it a few months from now.

Hi Robin,

	Where did you find the plans to make the wingtip NAV antenna?  I am

very interested in doing the same.



Thanks,

Turns out page 13-16 (Chapter 13, page 16) of the Aeroelectric

Connection has an excellent diagram:
