Easy guide to install GoTV external antenna 

You do not have to use the GOtenna that came in the box. A GOtv decoder can run off a standard external UHF antenna, the same kind used for normal digital TV, because GOtv broadcasts on a terrestrial signal that an ordinary aerial can pick up. This is genuinely useful if you already have a rooftop antenna, or if you live somewhere the small indoor GOtenna struggles to hold a signal.

The whole job needs just one cheap part and about ten minutes. Here is how to do it correctly, without the guesswork.

Why Use an External Antenna With GOtv

The standard GOtenna works fine in areas close to a transmitter, but its reach is limited. If you are far from the nearest GOtv tower, or your signal keeps dropping in bad weather, a larger external antenna mounted high on your roof pulls in a stronger, steadier signal.

It also saves money and clutter. If your house already has a UHF aerial for regular TV, there is no need for a second antenna on the wall. One antenna can feed the signal your decoder needs, as long as it is a UHF-capable digital aerial, which most modern ones are.

What You Need

The only part you must buy is an F-connector, also called a coaxial cable connector. It costs very little and is sold in any electronics shop. You will also need the coaxial cable running from your external antenna, and a knife or small blade to strip the cable end.

That is the whole shopping list. If your antenna cable already has an F-connector fitted, you may not need to buy anything at all.

How to Connect the Decoder to an External Antenna

Prepare the coaxial cable

Take the coaxial cable coming from your external antenna and strip about a centimetre of the outer plastic sleeve from the end. Underneath you will see two conductors: a solid copper wire in the centre, and a layer of thin braided wire or foil shielding around it. These two must never touch each other, since that causes a short and kills the signal completely.

Fit the F-connector

Twist the F-connector firmly onto the stripped end of the cable. The solid centre wire should pass straight through the middle of the connector and poke out slightly at the tip, while the braided shielding folds back and grips under the body of the connector. A firm, clean fit here matters more than anything else, since a loose connector is the most common reason people end up with zero signal after wiring everything up.

Connect to the RF IN port

Find the port labelled RF IN on the back of your GOtv decoder. Screw the F-connector into it clockwise until it is hand-tight. Do not force it with a tool, since the thread is fine and easy to damage. This RF IN port is the correct one for a single antenna feeding a single decoder. Leave the RF OUT port alone, as that is only for sending signal on to a second TV.

Scan for channels

Switch on the decoder and TV. Press Menu on your GOtv remote, open Advanced Options, then Installation, then Tuning, and run an Automatic Scan. Let it finish without interruption. Once it completes, your GOtv channels should appear as normal.

Checking Your Signal Is Strong Enough

After connecting, confirm the signal is healthy before you fix everything permanently in place. Press Menu, go to Advanced Options, and open Signal Information to see strength and quality readings.

According to GOtv’s own installer standards, a good signal sits between 75 and 100 percent, which means everything is set up correctly. A reading between 50 and 75 percent means the antenna needs better alignment or a higher position. Anything below 50 percent will cause channels to drop out or the picture to break up. Aim to get both readings above 75 percent before tightening the antenna down for good.

Getting Zero Signal After Connecting

If your strength reads 0 percent after wiring everything, work through these in order. First, unscrew the F-connector at the decoder and check the centre pin. If it looks too short to reach inside the port, strip back a little more of the cable coat to expose more of the copper wire, then reconnect. This single fix solves the majority of zero-signal cases on a fresh connection.

Next, check that the braided shielding is not touching the centre wire anywhere, since even one stray strand causes a short. Then confirm the antenna itself is pointing toward the nearest GOtv transmitter with nothing major blocking its path, such as a wall, roofline, or tree.

Do You Have to Use the GOtenna?

No. The GOtenna is simply what GOtv includes in the box for convenience, but the decoder does not care where the signal comes from as long as it is the correct terrestrial UHF signal. Any decent UHF digital antenna will work, which is why an existing rooftop aerial can do the job.

What matters is signal quality, not the brand of the antenna. A well-positioned external antenna will almost always outperform the small indoor GOtenna, especially in remote areas or places with weak coverage. If your channels ever disappear after switching antennas or subscriptions, our guide on how to recover lost GOtv channels covers how to bring them back.

Connecting a GOtv decoder to an external antenna is one of the cheapest upgrades you can make to your setup, and it often fixes signal frustration that the standard GOtenna simply cannot handle. Get the F-connector firmly fitted, run the cable into the RF IN port, aim for that 75 percent signal mark, and you are set.
