Description
The 4-70-54 notch filter installs quickly and easily via standard BNC bayonet couplings, in-line between radios and antenna. The 4-70-54 rejects in excess of 50dB of 1575.42 signal at the source. Each filter is individually tuned and checked to assure maximum performance.
An aircraft GPS receives its positional information at 1575.42 MHz while communications radios on-board typically broadcast in the 121.5 MHz range. The 4-70-54 filters the wide separation in frequency bandwidth and communications noise at the GPS frequency.

Frequently asked
Does the Inline GPS Notch Filter/Bnc 4-70-54 include certification paperwork?
This item is supplied as "Condition disclosed" rather than with full 8130-3 traceability — normal for some condition codes, and it does not mean the part is unusable, only that the paperwork profile differs. Check the listing for exactly what documentation is included, and request any available records before you purchase if your installation requires them.
What condition is this part?
This part is listed in condition NE — Condition disclosed. Condition codes describe how a part reached its current state (for example new, overhauled, serviceable, repaired, or as-removed) and directly affect what paperwork ships with it and how it should be installed. See the Glossary for the full definition of every condition code we use.

This item is in stock and ships promptly, usually the same or next business day once your order and payment are confirmed.

Can I return it?
You may return this item within 30 days of delivery if it is unopened, uninstalled, and in its original packaging.
