Been a while since I posted here, but I just noticed I don't seem to be picking up the ground side too good right now. Does anyone know how long it's been like that? I can't remember if I tried the antenna in all possible positions or not. I wonder if rotating it would make that much of a difference? I really want to get a second antenna and 3rd scanner to split up ZNY/KWRI feed. Does anyone have any suggestions for the best antenna to pick up the ZNY and KWRI frequencies?

On another note, if you notice problems with the feed, please try to send me a PM or reply to this thread, because I don't check this forum all that frequently. I do check my emails regularly, so the email notification will tell me there's something wrong, and I'll get back to fixing it ASAP.

Rotating that antenna is unlikely to do much of anything, John.  The issue is more likely a local noise level issue - something that could take a lot of debugging and that may not be easy to cure.  It could also be a change in setup on the base station (ATC) end.  They've been revamping a lot of equipment - and depending on a number of factors it could have made things more marginal.  If I recall that signal was right on the edge anyway.

From this vantage point it is all guessing.  Those broadband antennas are not ideal for optima ATC reception.  Better to use one tuned for VHF airband - but even that is no guarantee of picking up any particular ground station.  It's all about stacking the odds in your favor.

The feed lost ZNY-CAMRN (118.975) ground reception about 5 months ago (Late spring ish)

Is it possible to make an antenna that would be good for these ATC frequencies? I'd really like to try to improve the ground-side reception, but don't want to go spending a lot of money on an antenna that may not even help. Is there anything else I could try to do besides changing the antenna? Of course it probably doesn't help that my house is surrounded by trees. Oh, I forgot to mention that I had to lock out 372.200. I was picking up nothing but static, and if I adjusted the squelch to fix 372.200, the scanner wouldn't pick up the other frequencies too good.

Hi John, yes it's possible to build your own antenna.  I copied this information from another thread:

*******
A quarter wave ground plane antenna is easy to make for less than $5.  You'll need a soldering iron and solder too.
Shopping list:
11 ft of 12awg solid wire(not stranded)
SO239 connector (Radio Shack No. 278-201)

Cut the wire into equal lengths of 23 inches
Insert one wire into center of the SO239 connector and solder it into place.
Make a loop in the other four wires and loop them into the four holes in the SO239 connector
Solder the four wires in place perpendicular to the center conductor wire.
NOTE: This will be about 70 Ohms.  Ideally you want 50 Ohms.  To get 50 Ohms you need to be at 135 deg from the center radial
Make a loop in the center conductor wire so you can hang it by string or rope. 

This is a great attic antenna and it works very well.  The 50 Ohm version is what I use for the KHSV feed.

Link to how to build it but use my wire lengths:

I never tried this myself but I thought I'd pass it along.  I hope this helps...

I'll have to try that. I might even have enough wire laying around already. Hopefully it will improve the reception. For $5, it's worth a shot.

Just in case anyone is wondering, I ordered the connector last night, so I will give that antenna a try when it gets here.
