I’m all for the easy life, especially when we’re away in the caravan. After all, this is supposed to be a time for relaxation and being lazy if you want, isn’t it?
We have a caravan TV, for occasional viewing, when there is something specific that we want to watch, or for those days when the weather turns miserable.
Our latest tourer came with the Vision Plus VP3 Digital TV and Radio Amplifier, which was fine, but with the VP3, it’s a case of switching it on and a blue light illuminating to show that it is indeed on, but nothing else. To get the best TV signal means one of two things.
If you’re looking for an aerial for your ‘van too, be sure to take a look at our best caravan TV aerial guide, where we share our top picks on the market.
Best picture
You’ll either be slowly rotating the Status antenna while it’s connected to the TV and then waiting until you get the best picture – and sometimes that means doing this with the antenna in the horizontal position, then the vertical.
Otherwise, you can use a handy phone app, Antenna Aligner, which tells you where the best signal is at your caravan park, and whether the antenna needs to be in the horizontal or the vertical position, and which direction it needs to be pointing in.
I’ve also used the Labgear DVB-T signal finder, which has a series of LEDs (the more that light up, the better the signal).
Although the latter system should give the best signal, the problem is that you need so many hands to operate it – one to turn the antenna, one to hold the phone to see the direction to point the antenna in, and a third to hold the signal finder so you can watch the LEDs!
Signal finder
These ways of getting a TV signal are fine, but given my lazy nature, there is a better way. I still use the phone app, but I recently swapped the Vision Plus VP3 for the same company’s VP5, which has a built-in signal finder.
After checking the app to see which orientation the antenna needs to be in, and obtaining a rough indication of where the best signal will be, with the VP5, it’s simply a case of turning on the unit and then rotating the antenna into the best position, using the built-in LED as the indication.
When the signal is poor, the LED is red, going to yellow as it improves, and finally to green where the signal is strongest.
Sometimes, however, the signal in some areas is weak, so the best you’ll get is yellow, but even with that, you should get a picture on the TV.
If your caravan has a Vision Plus VP2, a direct replacement for that, with the signal finder, is the VP4 unit.
Changing a VP2 for a VP4, or a VP3 for a VP5 (or as I did on our previous van, a VP2 for a VP5) is a very simple task, taking just a few minutes.
Prepare the swap
Start by disconnecting the caravan battery, and any mains supply, and remove the fuse from the solar panel if fitted. Unscrew all of the leads into the amplifier. Sometimes these will need the help of a pair of thin-nosed pliers or a 10mm spanner, but I’ve usually found they are no more than finger tight. There could be up to five, although ours had four: antenna in, radio, TV1 and TV2 (the fifth is TV3). The first two are self-explanatory, and in ours, TV1 is the feed to the lounge, and TV2 to the bedroom.
You can mark each lead as you undo them (masking tape will do), or as was the case with ours, they remained in the order in which they were removed.
The plug that powers the unit needs to be removed, too. This will simply pull out.
Although the VP5 unit is also supplied with a new plug, there is no need to change anything – it’s exactly the same as the one for any of the other units and it’s already wired in.
With all the leads – including the power lead – removed, it’s time to remove the two screws (one at either end) of the VP3 and remove the ‘old’ unit from its mounting (usually just into the inner wallboard of the van).
Fitting the VP5
Installing the VP5 is simply the reverse of removing the VP3. Start by attaching the unit to the mounting. If it is into the caravan wallboard, be careful not to overtighten the screws.
Attach each of the leads to their respective connections. Finger tight is often enough, but I also gave each of ours a tweak with a pair of small pliers (I didn’t have a suitable spanner to hand). Finally, plug in the unit’s power lead.
With the caravan battery reconnected and the fuse to the solar panel reinserted, it was time to test the VP5.
Sadly, we live in a fairly weak signal area, but the LED did change from red to yellow before going back to red as I rotated the antenna. Even when it was yellow, the signal was good enough to receive a fairly decent picture on the TV.
When I checked the new unit against the handheld signal finder, it was reassuring to see that both the VP5’s indicator and the handheld corresponded.
Job done! And now I can tune in the TV with one hand while holding a glass of my favourite tipple with the other…
How to upgrade a TV amplifier – a step-by-step guide:
1. The VP3 as supplied with the caravan.
2. The Labgear DVB-T signal finder.
3. Antenna Aligner smartphone app.
4. The new Vision Plus VP5 unit.
5. Remove all leads, including power plug.
6. Next, remove mounting screws.
7. Mount the VP5 using the same screws and holes (be sure not to overtighten).
8. Attach the various leads to the VP5 and nip them up with a small pair of pliers
9. Testing the VP5 shows that the LED indicators are functioning.
