[RFI] ANC-4 FOR SALE

[WA3GIN]

Hi Folks,

Moved to the country...no more city noise to deal with... have two JPS-ANC 4 units for sale; one set-up for PTT.
The ANC-4 was originally developed by JPS, but is now being manufactured exclusively by Timewave. It is an RF device designed to provide cancellation of locally generated noise from signals received by a primary antenna. 

The unit is employed right at the antenna connector of the receiver to cancel noise from power lines, computers, TVs or nearby equipment. This device cancels locally generated noise before it reaches the receiver or transceiver. Front panel controls are provided to allow adjustment of both phase and magnitude of the local interference, providing extremely deep cancellation of the offending noise. May also be used with transceivers with RF power under 250 watts PEP. The built-in telescopic whip is used by the ANC-4 to receive the nearby noise it is going to cancel. There is also an RCA jack to connect a larger noise monitoring antenna if desired. Click here to view connection diagram 

Operational range:  500 kHz to 80 MHz. The rear panel standard SO-239 connectors for antenna input and output. Size:  6W x 1.7H x 4.3D inches. Requires 12 VDC @300 mA. The optional AC-1 power supply may be used. Earlier production units had a built-in telescopic noise antenna. Current production has a supplied wire antenna. 

Please respond direct:  Price shipped w/power supply and manual. $165.
