FM Band Stop recommendation

[batdude]

ebay is too full of junk it seems... and sorry (not sorry) i prefer to not install something that says "made in china" in line with my gear....

i need a recommendation for a good FM trap (band-reject) / notch filter.... i am getting some splatter in the lower end of the VHF Air band that is very annoying... seems to be from a station in the 105.xxx MHz range.

note that i can't have the filter encroach on 118.xxx MHz too much (0.5-1db max)


anyone have a decent recommendation?

PAR electronics, hands down. Quality stuff - you get what you pay for

Loss is pretty lo on VHF air.

I should also note that, at least at one time, RS sold their own FM trap which several folks here found very effective. Whether they still do or not, I don't know.

You could first try a less costly solution and get both a low noise amplifier and a filter from GPIO Labs in Canada. It will both increase reception and stop FM splatter. Also use a 20dB variable attenuater to adjust the gain if the scanner gets overloaded.

IF interested and near a closing Radio Shack, see if they still have 1500024 (you won't find it online anymore) it is an FM Trap, altho it is 'F" coax connectors, you can also get those and a 3-6 foot short cable to connect to the BNC for the scanners.

I find they work quite well., got the last Trap at my Local RS for $1.00

Another store I was at had 5 of them, almost bought them, but am waiting for the 80% sale
