Frequently Asked Questions - ATM301 UNIDEN

How do I install the Uniden ATM301 antenna?

Mount the antenna on a mast or wall using the included bracket. Point it towards the nearest TV transmitter. Connect the coaxial cable to your TV or set-top box. Use a signal meter for optimal alignment.

What is the best position for the antenna?

The antenna should be placed as high as possible, preferably outdoors, facing the broadcasting tower. Avoid obstructions like trees or buildings. Use a compass or app to find the correct direction.

Does the ATM301 work for digital TV?

Yes, it supports DVB-T/T2 digital terrestrial television. It receives both VHF and UHF bands, covering most digital channels.

Can I use this antenna indoors?

It is designed for outdoor use, but can be used in a loft or attic. Performance may be reduced indoors due to signal attenuation.

How do I clean the antenna?

Wipe the antenna with a soft, dry cloth. Do not use water or solvents, as they may damage the elements.

Is the antenna weatherproof?

Yes, it is built to withstand outdoor conditions, but ensure connections are sealed against moisture.

What type of cable does it use?

It uses a standard 75-ohm coaxial cable with an F-type connector. The included cable is approximately 10 meters long.

Can I amplify the signal?

Yes, you can add an optional masthead amplifier if the signal is weak. The antenna is passive but compatible with inline amplifiers.

Why am I not receiving some channels?

Check the antenna alignment, ensure all connections are tight, and rescan your TV. Obstructions or distance from the transmitter may also affect reception.

Where can I find spare parts?

Spare parts like mounting brackets or replacement elements may be available from Uniden or third-party suppliers. Contact Uniden support for assistance.

VHF MARINE\*

Ideal for the safety of recreational boaters for ship-to-ship or ship-to-shore communications. Uniden VHF Marine Radios operate in the VHF Maritime Mobile Band on the frequency range between 156MHz and 162MHz. All Uniden VHF Marine Radios can communicate on the VHF distress & emergency channel 16, and receive local weather and navigation warnings on VHF channel 67 – the latter dependant on the local broadcast schedule. Modern VHF radios have the additional feature of Digital Selective Calling (DSC) that allows distress alerting at the push of a button.

27MHz MARINE

Suitable for recreational boaters for use in enclosed waters, the 27MHz Inshore boating radio service band is unique to Australia. Used for ship-to-ship and ship-to-shore communication, and capable of distress alerts on 27MHz channel 88 and receiving weather forecasts and marine safety information – provided that the vessel is operating within the coverage area and times of the volunteer services.

*An operating certificate (SROCP) is required to use a VHF radio. A fee is normally required for certification. More information about licensing of radios and operators can be found at the ACMA website.
