Delta4 C

Here is a clever idea from Alpha Delta!

The Delta-4C and Delta-4CN are desktop antenna switch consoles. These switch consoles sit next to your rig without having to be installed on a wall or screwed down on a desk top. They are true consoles and maintain the Delta-4 precision design. The cast housing and connector arrangement is designed to prevent cables from pulling them backward off the desk. The powder coated heavy black housing makes a beautiful addition to your station.

These precision antenna switches employ the latest high-tech design. Cast aluminum constant impedance cavities permit the switching of two or four antennas while maintaining a constant 50 ohm impedance. Silver-plated phosphor bronze micro strip construction ensures loss of less than 0.1 dB at 30 MHz with greater than 60 dB of isolation (0.5 dB loss and 50 dB isolation at 450 MHz). The Delta switches offer three levels of surge protection! In the common position the common is disconnected from all antennas and all antennas are connected to ground. These switches feature a built-in surge protector. A replaceable D-4 Arc-Plug cartridge will divert harmful surges to ground. The Arc-PlugŪ Cartridge Pill will not operate without a good ground. It is also good practice to ground the coax shield at point of entry to the building. (Note: The Delta switches reduce the hazard of lightning induced surges, but will not prevent fire or damage caused by a direct strike). Made in the U.S.A.

The Delta 4C console features four SO-239 fittings (for PL-259s).
The Delta 4CN console features four N fittings.
