While it is true that those will play the biggest factors as I understand it (the main one in fact making sure to point the aerial in the right direction / adjusting it), this booster so far (after only a few days of use), seems to have been able to get things over the line. HD channels in particular for myself would suffer with pixelation occasionally, which would also interrupt scheduled recordings. The TV we use (which has the recording facility built into it) also has an auto tune feature that can be set to periodically scan for channels when in standby. This is useful so new channels are detected and the guide list of channels remains up to date without manual input, but also means that if channels are no longer detected at all, then they are removed and scheduled recordings are also removed / forgotten. As such, this booster has seemingly thus so far stopped the pixelation by significantly improving both signal quality and bettering the bit error level, and channels have remained after the auto scans. I have chosen to power this via a socket USB port so it always has power, as those in the TV power down when in standby, so the auto tune feature as mentioned would likely be effected by a reduced signal (quality and strength) meaning channels would be lost when the booster was not actually fully boosting the signal when the TV was otherwise in standy. All in all this booster thefore appears to be doing a good job. It is small too. The 3M pads provided were no good for sticking this to the back of a TV with a slightly bumpy texture, but that was easily resolved with Nano tape instead, and this sits neatly now out of the way doing it's job. On a side note, I don't watch live TV much now but record the odd thing here and there and I do like to have things working correctly should I wish to use it (even if only occasionally). So for a small price this was worth it for me, as digital TV is likely to be here for a few years yet until the full switch over to streaming only is fully integrated.

Simple to fit and works absolutely perfectly, excellent ### ⭐ Didn't work, worsened reception *by I***S on 1 March 2025* I had high hopes for this as I didn't need much, it seems climatic conditions affect the reception so I just need an extra push. However, after plugging the device, all channels were lost. Tried rescanning but at first nothing was found. After several tries repositioning the device it started finding channels but less than without it and quality was just as it was without. It seemed just perfect in terms of size and just needing an USB port, but it just doesn't work for me unfortunately and had to return. ## Frequently Bought Together - SLx TV Signal Booster Aerial Amplifier, 1 Way Signal Distribution Amplifier with Coax Connections, 4G & 5G Filtering, Indoor TV Aerial and Freeview, Variable Gain Control - 2m Long TV Aerial Cable Right Angle with Plug Adapter - Coaxial Satellite Cable TV Antenna AV Lead Male to Male with RF Connector Coax Extension Gold - FreeView, FreeSat, Sky Box, BT - RELIAGINT TV Aerial Cable 0.5m – Pure Copper TV Coaxial Cable with Dual Shielding for Strong Signal – Straight or Right-Angle – Female-to-Female Adaptor Included – Fire-Resistant Aerial Connectors --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/517622273-tv-signal-booster-aerial-amplifier-1-way-signal-distribution-amplifier](https://www.desertcart.sn/products/517622273-tv-signal-booster-aerial-amplifier-1-way-signal-distribution-amplifier) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-06*
