  • Identify signal strength with easy-to-read LEDs
  • Find the strongest signal without use of Freeview box

Product overview

• Ensure you get the optimum TV picture from your aerial
• Identify signal strength with easy-to-read LEDs
• Find the strongest signal without use of Freeview box
• Signal range 60-90 dB
• For terrestrial aerials

Note: this Signal Strength Meter has F-connectors which match most modern aerials. To test older aerials, additional F-to-Coax adapters will need to be purchased (Maplin order code: QP41U)

Rated 2 out of 5 by from This unit works but: 1) You can't use it in line with Samsung TVs (they must short the ouput or something as all LEDS inc power go off when connected in line to a Samsung TV) 2) When connected in line, it causes approximately a 20% drop in digital signal strength and quality. This drop in quality then makes my picture unwatchable. 3) Other reviews saying just use the signal info from your TV, set top box or PVR are right.

Rated 5 out of 5 by from Hi. This unit is great, simply plugged in an caravan aerial on a long pole and used the power pack supplied, walked about outside the house, found a good signal area, then relocated my existing house aerial, freeview signal much better. This unit will be very handy looking for the best TV signal when we go caravaning.

Does the unit need batteries?

Asked by: MalG
This uses a 9v battery, to remove you need to use a small flat scredriver to remove the back plate, there should be a very slight opening mark / indention.

Have Panasonic TV fed from a FreeSat dish for 10 years. Now TV started to lose  signal from BBC1 then all stations intermittently.I need to know if the problem is between the dish and the end of the aerial cable or within the TV.Will this unit do it ?

Asked by: TV less
This is for terrestrial aerials only, not satellite dishes. This item is also discontinued.

I've moved into a new house. There is a satellite dish and F-connector cable. I plugged cable in to the ANTENNA side and it didn't pick up any signal. Is this because there's no subscription being paid for (e.g. Sky) or should it still pick up a signal?

Asked by: Bradster
A signal will be picked up no matter what if both ends are connected to the correct cables, however this product only works for terrestrial aerials and not satellites.

Aerial lead in left of meter & lead to the set top freeview box in right side pressed the red button & got a flash from the 60db led then it went off (power light stayed on) - Picture quality looks good - Should led stay lit? - Do I need signal booster?

Asked by: homeric
A signal booster is not needed if the the picture quality is good, The Led is just the signal strength indicator that shows the strength of the signal that the aerial is pointed at any one time.

can this device be used just connecting it to an aerial and nothing else to align the aerial 

Asked by: ffff
Yes this can be used on its own to find a signal however it should be connected to a free view box too.
