Average Reviews:
(More customer reviews)This is a comparison of the SDV5122/27 (amplified) vs SDV2710/27 Philips antenna.
The amplified SDV5122/27 (means you have to plug into a 120V outlet) is not much better, if at all better than the passive (no power required) Philips SDV2710/27 antenna.
Comparison - same location (in a window), same TV, same day (15 min of each other),clear weather
Location - about 21 miles from transmitters, first floor window facing transmitters.
Function -
For UHF signals/stations, the SDV5122/27 is slightly better and pulls in a few more stations, but the SDV2710/27 pulls in all the major stations, just not a few fringe stations.
For VHF signals/stations, Actually, the single dipole (the stick antenna part used for some VHF channels, such as ABC in my area)on the SDV5122/27 is a disadvantage for this unit, requiring lots of tweaking to get some sort of picture, but still not good enough to be free of image issues. Holding the end of the dipole antenna gives you a great picture though :(
(go to [...] to see which stations in your area use VHF and UHF)
Appearance - the SDV5122/27 is the winner here, looking more sophisticated and compact, with a better stand. In both cases, the dipole antenna(s) have to be extended, which are not shown in the photos, adding a few feet to the height of the antennas.
Connection - both have a 6ft antenna cable, however, for the SDV5122/27 it is removable, making it easy to buy a longer cable to put it near a window. With the SDV2710/27 the antenna cable is permanently connected to the unit, so you need an adapter to add extra length (and looses some signal with the adapter addition)
Energy use - the SDV2710/27 is passive, meaning that there is no energy use, so it's use if free after your purchase price. The SDV5122/27 however, is amplified, which means it has a power adapter (white with white cord) that you have to plug into a 120V outlet for it to work. Power draw is only given in amps (0.2A)but if you do a rough calculation, that means it uses 24Watts, plus you have to plug it in and unplug it if you want to save energy. It is energy level V, which is the energy star level, however, that only applies to when the product the transformer is powering is "off" and since the antenna never turns off, the transformer is always supplying full power (even if the TV is off)to the Antenna
Stand - the SDV5122/27 has a better stand, the SDV2710/27 is not bad, but you have to either extend the foot on the bottom (if you do not know it is there, you will never see it, it folds out) or shape the antenna like a V to hold it up.
Price - when I bought the SDV2710/27 it was about $10 less than the SDV5122/27, but now the SDV5122/27 is less. (you can go to the manufacturer's site for a lower price on the SDV2710/27)Other notes -
Digital Antenna are not as easy to use as the old analog ones, and what is good for one person may not work in your application due to distance from transmitters, tall buildings, tall trees, direction that your antenna faces, and if you have aluminum siding or not (aluminum siding can block signals from reaching the indoor antenna).
My experience with these two antenna and an old rabbit ears that I have is that the best location is right in front of a window, anywhere else it is hit or miss and hard to get all stations without having to move the antenna around.
