Top Antenna Switches in Australia: UHF, Ham & 3-Way Options Explained
So, What’s an Antenna Switch Anyway?
If you’ve got more than one antenna or radio rig set up at home, in the shed, or even out in the 4WD, constantly swapping cables can be a pain. That’s where an antenna switch comes in handy—it lets you flip between antennas or radios with a simple twist or click.
You’ll find them everywhere—from amateur (ham) radio setups to UHF radios used by truckies, tradies, and emergency services across Australia.
How Do They Work?
Think of it like a railway junction. Your signal goes in one track (a radio or antenna), and the switch sends it down whichever track you choose. Whether it's a single switch between two antennas or a 3 way antenna switch that gives you even more flexibility, they’re super useful.
Why Use One?
-
You’re using different antennas for different bands
-
You want to quickly switch between base and mobile radios
-
You’re trying to avoid wear and tear from disconnecting coax all the time
-
You want to keep your setup neat and tidy (no more cable jungle!)
Why UHF Antenna Switches Are Big in Australia
UHF radios are a go-to here in Australia, especially with all the off-road driving, remote work, and bush travel. Whether you’re chatting with mates on the tracks or coordinating jobs on site, UHF is rock solid—and a UHF antenna switch makes it all that much easier.
When Would You Use One?
Let’s say you’ve got a stubby antenna for town driving and a tall whip for the open road. Instead of swapping them manually, plug both into a UHF antenna switch and flick between them as needed. Too easy.
Other Perks
-
Keeps signal quality strong
-
Reduces damage to cables from constant twisting
-
Some models are even weatherproof—great for mounting outside
3 Way Antenna Switch: A Handy Bit of Kit
If you’re someone who likes to experiment with setups, or you’ve got a bit of a shack full of gear, a 3 way antenna switch is a no-brainer.
Why Go 3-Way?
-
Quickly switch between three radios or antennas
-
Useful in contests or emergency comms
-
Keeps everything connected but isolated—no cross-talk
They’re popular with ham radio operators, but even CB and scanner users can make good use of them.
Ham Antenna Switches – Built for the Serious Operators
For ham operators (you know who you are), an antenna switch isn’t just a nice-to-have—it’s essential. Whether you’re chasing DX, tuning into local nets, or just fiddling with antennas (because let’s be honest, it’s half the fun), a ham antenna switch is part of the toolkit.
What to Look For
-
Good power handling (especially if you’re running a bit of juice)
-
Solid connectors – none of that wobbly junk
-
Minimal loss – you want that signal nice and clean
-
Some sort of grounding – helps avoid lightning drama and static buildup
Plenty of Aussie hams swear by brands like Daiwa, MFJ, and Diamond—all of which you’ll find at Comtek Radio.
Setting It All Up – A Few Quick Tips
-
Mount the switch where you can reach it easily – you’ll be using it a lot
-
Use proper coax – RG-58 might be cheap, but it’s not always the best
-
Keep runs short – especially on UHF, every metre counts
-
Ground it properly – better safe than sorry in a storm

FAQs – Quick Answers to Common Questions
1. Can I use the same antenna switch for HF and UHF?
Not really. They're usually tuned for specific frequency ranges. Best to get one rated for what you’re using.
2. Are 3 way antenna switches hard to install?
Not at all. Plug and play in most cases. Just check your grounding.
3. What connector do I need?
Most ham and CB gear uses SO-239. But check your rig—some modern gear uses BNC or N-type.
4. Is there any signal loss with a switch?
A tiny bit, but with a good switch, it’s almost unnoticeable.
5. Can I leave it outside?
Only if it’s built for it. Look for weatherproof or waterproof rated switches.
6. Can I get one with lightning protection?
Yep! Some models include built-in grounding or lightning arrestor features.
Wrap-Up: Choose the Right Antenna Switch for Your Needs
