Clear the way for improved reception and a stellar entertainment experience by adding a Philips LTE Filter to your home entertainment system.

Review: Cheap and works as promised - For those who don't know what this product is about, a quick (simplified) summary of major changes to Over-the-Air Television in the United States. UHF TV reception in the US originally consisted of channels 14 to 83 (460 to 890 MHz) introduced through FCC regulation in 4/11/1952. The 800 MHz portion (channels 70 to 83) of the UHF TV band were reallocated already back in 1983 for other services (including but not exclusively to mobile telephone service). Effective 6/12/2010 (immediately following the Analog to Digital TV conversion) the 700 MHz portion of the UHF TV band (channels 52 to 69) were auctioned off by the FCC of which AT&T (band 12, 699 to 746 MHz) and Verizon (band 13, 746 to 787 MHz) were the major winners. Since then the FCC conducted a "repack" requiring TV broadcasters to move from upper UHF channels to lower UHF channels or back to VHF (were many stations were broadcasting prior to the Analog to Digital TV conversion), including to the low-VHF band that was originally deemed unsuitable for digital television. In 2017 the FCC then auctioned off the 600 MHz portion of the UHF TV band (channels 38 to 51) of which T-Mobile was a significant winner (band n71, 617 to 698 MHz). TV broadcasters had until June 2020 to complete their relocation and to free up the 600 MHz spectrum. TV channel 37 has been and continues to be a reserved channel for radio astronomy which means that the usable UHF TV band has shrunk to channels 14 to 36 (460 to 608 MHz). All of the above refers to the actual RF channels on which your local stations really transmit (which has absolutely nothing to do with the channel numbers your TV will display). Depending on how old your TV tuner is, it will be designed to receive signals from the 600, 700 and possibly (so less likely) 800 MHz ranges which no longer contain any TV programming. The mostly mobile phone transmissions on those bands can interfere with the TV programming you are actually interested in. To prevent nearby cell towers and even your own cellphones from interfering with your TV reception, a number of companies make filters to block the unwanted signals from getting into your TV. This product (Philips SDM1520/27) is one of those products. It was half as expensive as a similar product (ChannelMaster CM-3201 also here at desertcart) which I also purchased. Needless to say, I was curious whether or not the higher price of the CM-3201 was worth it and I wanted to rely on science instead of subjective testing (e.g. how many times a particular channel pixelates within an hour). I therefore used a NanoVNA-H4 to measure the filter characteristics. I'll state upfront that using test equipment for 50 Ohm impedance with 75 Ohm impedance filters does introduce some errors into the measurements, however since this is the same impedance mismatch in both cases it still results in a valid comparison. An ideal (impossible) filter would have no attenuation below the cut-off frequency and infinity attenuation for any frequency above it (meaning that there would be no transition band at all). Real filters reveal their quality by how much they attenuate unwanted signals and how wide the transition range is (the frequencies between start of attenuation and full attenuation). Both filters showed a start of attenuation at 606 MHz (first visible sign of attenuation in the LogMag trace, not the 3dB attenuation commonly used to characterize filters) which is still within the frequency range for TV channel 36 (I subsequently tested the filters on a local station that uses RF channel 36 and the reception was fine). Also both filters showed reasonably low figures for insertion loss (the attenuation of a good signal just because the filter is being added). The ChannelMaster CM-3201 showed a transition band of 36 MHz (less is better) and attenuation of nearly 60dB (more is better, but 60dB is already excellent). The Philips SDM1520/27 (this product) showed a transition band of 72 MHz (a bit disappointing that it is so wide) and attenuation of about 30dB (which is good, but higher would be better). In-line filters are often symmetrical and can be used in either direction. Both the CM-3201 and the SDM1520/27 have explicit input and output markings but I did not test whether the filters behave any different when used backwards. The Philips SDM1520/27 is significantly smaller in diameter which may be an advantage on some TVs with recessed antenna connectors. Bottom line, this filter does work and while it is not as impressive as the more expensive one I compared it with, keep in mind that it only costs half as much. I don't see any reason to deduct a star in rating just because a more expensive product has better test results. Not everybody may need these filters (locations of TV and cell transmitters play a big role) and if you do, you may get satisfactory results from this cheaper filter. If you are concerned about getting the best results spend the extra money on the ChannelMaster CM-3201. However beware of any filters that are still sold which are based on the 2010 elimination of the 700 MHz band since those are not blocking cell transmissions in the 600 MHz range.
Review: It worked! - I live in Chicago, and I'm pretty close to one of those cell phone towers, (less than a mile) and since its started warming up here again, my tvs have started acting up again, as they do every year at this time. It's a combination of the big trees on my street getting their leaves again, the cell phone tower thing and an increase in the humidity, at least that's my theory. I put this on one of my tv just to see what happened, and as God is my witness, it stopped the picture pixelation, and NBC, CBS and WGN, which wouldn't come in at all during the mornings, now come in at a higher signal quality. Some of the channels actually come in at the same signal quality as the signal strength, which is 100%, which has never happened before. The signal strength was always 100% on all of my channels, but the signal quality would vary from channel to channel and most times it would jump around to different percentages on that specific channel, but never reach a steady level, much less 100%. During the cooler months things would improve, but certain channels still wouldn't act right completely. All that I can say is that I'm impressed, because I bought an open box one, just in case it didn't work, I wouldn't sweat it too much, but the dog gone thing works, so I'll be purchasing a couple more for my other two TVs soon.

## Questions & Answers

**Q: Does it work as a High Pass Filter ?**
A: I haven't torn one apart, but I suspect it's a simple finely-tuned a tank circuit that shunts specific frequencies to ground (a simpler method than blocking) which would be considered a notch filter vs. a high or low pass filter. In either case, it works very well for me.  I live next to a call tower, and due to our proximity, we couldn't get any more than a few channels.  Once the filter was placed between the antenna and our distribution amplifier, we jumped from a handful to over 70 channels now available.

**Q: what is the rejection (in dB) and what is the insertion loss (in dB)? All traps/filters must have at least some insertion loss, even if it's .5 dB.**
A: With a 4' antenna cord rejection is .1 to .3 and loss is .5 to .8 depending on connection type.

**Q: Does this only work for amplified antennas?**
A: Thank you for your question.  It works for both amplified and regular antennas, but if your antenna was purchased in 2020 or later it should have a filter built in already.

**Q: does it fix radio fm recept?**
A: No. It is a cell signal filter for a tv antenna. It's only made to improve tv reception more so if you are close to a cell phone tower.
