📡 INTEGRATED DAS DUAL ANTENNA SYSTEM

The feature that makes the UHF182XP different from a conventional UHF CB radio is its integrated Dual Antenna System.

The rear of the transceiver includes two separate antenna connections:

• 📡 ANT1 – 50 Ohms
• 📡 ANT2 – 50 Ohms

This allows two compatible UHF CB antennas to be connected directly to the one transceiver.

The system is designed to automatically receive the strongest available signal from the connected antennas, removing the need to manually switch between antennas when conditions change.

---

🏜️ WHY USE TWO DIFFERENT UHF ANTENNAS?

No single antenna gain is ideal for every terrain type.

A touring vehicle may benefit from carrying:

• 📡 A lower-gain antenna for hills, valleys and heavily undulating terrain
• 📡 A higher-gain antenna for flatter open country and highway travel

The UHF182XP allows both antennas to remain connected to the radio at the same time.

Instead of stopping and physically changing antenna connections or adding an external manual switch, the integrated system can make use of the available antenna inputs when receiving signals.

This makes the UHF182XP especially appealing to customers who regularly travel between:

• ⛰️ High country
• 🏜️ Open outback terrain
• 🛣️ Highways
• 🌲 Forest tracks
• 🚙 Rough and undulating off-road terrain

❓ FREQUENTLY ASKED QUESTIONS

What makes the UHF182XP different from a normal UHF radio?

Its biggest difference is the Integrated DAS Dual Antenna System. The radio has two antenna inputs and can automatically receive from the antenna providing the strongest incoming signal.

Can I connect two UHF antennas at the same time?

Yes. The UHF182XP has two separate 50-ohm antenna connections on the rear of the transceiver.

Do I need an external antenna switch?

No separate manual antenna switch is required for the integrated Dual Antenna System described for the UHF182XP.

Does the radio automatically choose the better antenna?

For received signals, yes. The system is described as automatically receiving the strongest available signal from the connected antennas.

Does it automatically transmit through whichever antenna is best?

The supplied technical information specifically describes automatic strongest-signal selection for reception but does not explain transmit-antenna selection behaviour. That should be confirmed from Oricom's operating instructions rather than assumed.

Why would I want two antennas?

Different antenna gains can suit different terrain. A lower-gain antenna can be useful in hilly or heavily undulating country, while a higher-gain antenna is generally attractive for flatter, open terrain and highway travel.

Could I run a low-gain antenna and a high-gain antenna together?

The radio is specifically designed to accept two compatible 50-ohm antenna inputs. Using different suitable antenna configurations is a logical way to take advantage of the system when travelling through varied terrain.

Is a higher-gain antenna always better?

No. Higher gain concentrates more of the antenna's radiation pattern toward the horizon, which can suit flat terrain. Lower-gain antennas can provide a more useful vertical radiation pattern through hills and steep elevation changes.

Does the UHF182XP come with two antennas?

No. Antennas are not included.
