Looking for high quality and no-nonsense, we approached several engineers for various product design work. For the RF Choke filter, one company we chose is Array Solutions. They do quality work. A current balun that works well with our vertical antennas is their RFI line isolator. The ratings say it all. Plug it and leave it. Enjoy the bands worry-free with your friends.
Ham radio is fun again!
AS-50-L1 - 50 Ohms RFI Line Isolator, SO-239 connectors, 5 kW CW / 10 kW SSB, 1.8 - 30 MHz
These current devices are based on the W1JR Baluns. They are used to stop RFI on the outside of a coaxial cable shield from entering a radio shack. They also are used to isolate vertical feed points to eliminate coaxial cable RF pickup.
Pairs well with Greyline DX Flagpole and DX Vertical Antennas.
Key Benefits:
- Feedline is decoupled from a vertical antenna radial system
- Rejects feedline radiation into sensitive areas of the radio room
- Perfect for raised radial systems to prevent feedline from coupling to the radials
Features:
- 50 Ω unbalanced to 50 Ω unbalanced current isolator
- Rated for 5 kW CW and 10 kW SSB, these isolators offer the same quality as the well known W1JR baluns.
- VSWR 1:1 for 50-ohm devices
- Teflon SO-239 on either side of the box, also available in N-type and 7/16DIN
- 4" x 4" x 2" NEMA 4X Sealed boxes
