Magnum Dynalab do not recommend me to use ST-2
 
3 Attachment(s)
Hi,
After discussion with MD, they do not recommend
Me to go with ST2, due to location of my home which is
1. In big city where lots of tall building surrounding my home.
2. Station is very close to my home around 3 miles.
MD worried about multi-path reception and the lack
Of line of sight to station as difficult for the antenna to work effectively.

Currently I use Terk Edge+ with pretty good result
Most of the time.

Here are attached pictures of where I live and where I initially planned to install ST-2 .

FM reception can be tricky in urban areas. Tall buildings can be a hindrance, although it's likely that the actual antenna height exceeds the height of the building between you and it, and that should help. When you say your present arrangement works "most of the time," can you tell us what happens when it isn't working well? Is it weather related? Something else?

I use an antenna that's no longer available that's similar to the ST-2, except it is tuned to the 88-92 band. I live a few miles from all the big station transmitters in Chicago so those aren't an issue to pick up even with a dipole. However, my reception has improved to the public radio band w/this antenna. If you mostly listen to your local stations, I'm sure you are fine with the Terk.

During daytime the reception can be broken and very noisy. I have to rotate the Terk a lot and try to move it up and down to find that fine line.
At night, most stations are very clear and strong.
I think there are many illegal RF activities during the day
That frequencies are so close to radio stations. Or many electronics operating in huge office buildings interfere
With FM signal I don’t know.

But consider I spent plenty on cables that later I didn’t like and not use them anymore. Why not give 200$ ST-2 a try, if it create reception anomalies such as multi-path,or etc.. just disconnect it and leave it, much less damage than unhappy cables for sure.

Yes, Stations are all within 3 miles. But during daytime
TERK is broken and noisy on some stations.

Do you know the ERP of these stations?

The Terk is an amplified antenna, correct? It may be overloading your tuner's input. You might want to try using just a basic T-wire dipole antenna. It will be lower gain than the Terk and that might resolve your issue.

Typically, especially at close range, FM reception is pretty consistent.

You might also consider adding a Magnum Dynalab Signal Sleuth. While this is an FM signal amplifier, it also can de-amplify adjacent frequencies to help with multi-path. For example, if trying to capture 89.7, you can either set it to 89.7 and amplify the signal to varying degrees, or set it to 89.9 and depress that signal. The MD-205 runs around $500 new, but there’s a used one on USAudiomart for $200 at the moment.

That's a good suggestion. I had one of those many years ago when I lived in a different location. It was the original Signal Sleuth (not component width, but a boxy affair) but quite effective. It did add a little noise, but there's no such thing as a free lunch.

If you do decide to try the Signal Sleuth, I'd use a T-wire dipole where you live and not connect it to the Terk antenna.

I don't really know the ERP or knowing what it is.
MD205 is quite interesting in concepts.
TERK has amplifier but adjustable and I tried with the gain knob and tried rotated it
around despite being omni.

I think , as ST-2 is not that expensive at all I think I will give it a try.
and may use it indoor to reduce gain.

Got it anyway.
Still test indoor.
