| The following Amps are KNOWN to work with cable modems:
Electroline EDA2100 (Thanks, bouchecl
Electroline EDA2400 (Thanks, bmusgrove
(I'm assuming that the above are 1 and 4 port models, respectively)
Motorola Signal Booster Drop Amp - Model 484095-001-00 (Thanks, Cory Cooper
Scientific Atlanta Surge-Gap(r) Drop (Thanks, Me)
Pico Macom CDA-1A (Thanks, Charter tipster. currently $40 shipped).The following Amps DO NOT work with cable modems:
The inline amplifier sold at Radio Shack prevents 2-way communication. (Thanks, Chakthi
I do not have access to many amps. If you have an amp installed in your home, please provide me with the information for it and whether it works or not!
Feedback received on this FAQ entry:
- Great FAQ! Very helpful in learning more about my cable. Btw, I wired Signal Vision SVA15-2PRSV Amp today then ran the output through a 4-way splitter for all the rooms, and finally another 2-way splitter since my cable modem (SURFboard SBG900) and TV are on the same loop. So far internet and TV are working fine. Actually, TV signal was bad and now is great. The stats from the modem are:
Downstream - SNR: 38.2dB; Power: -1.8dBmV
Upstream - Power: 55dBmV (somewhat high but before I made changes was 54)
Anyway I thought I thank you and share that SVA15-2PRSV amp works with SURFboard SBG900 modem.
- One thing that I have learned out in the field is that if you are having issues with connections with your cable modem, Amps (no matter what kind it is) is just a patch and not a solution. Majority of the time, there is a cut, exposed wire, bad fitting (long stinger, sucked out fitting) causing the issue. If that's not the case, it can also be that the the Upstream level it's self is either too High or too Low. All modems should not need an amplifier to work properly. If it does, you may have some other problems what needs to be address and corrected before the problem gets worse.

- DataComm's new 70-0039 (1X8) coax HD distribution amp actually has a return gain amplifier - built in RF meter - individual 8 output adjustments - forward gain "step-up" amplifier. This is an awesome piece of equiptment specifically designed for HDTV.
- I have a few other amps that would be HSD/MTA compadable (2-way, some with Rx and Tx amplified, others just Rx). Any questions needing answers with amps, splitters, DCs, fittings, cable, etc. feel free to contact me. I am a Time Warner tech working out of the Central NY division and stumbled on this site browsing aimlessly. Any questions on digital phone, HSD services, cable/digital cable let me know. firstname.lastname@example.org
- Currently using a Qintar amp (supplied by Comcast) with cable modem and HDTV. Data and Specs: Residential Amp, RAMP2W-1000MS, 5-42MHz Return Path Passive, 54-1000 MHz Forward Path 10dB GAIN. Single in and out, powered via 12V DC 200mA transformer connected via Quad cable. Transformer input is 120VAC, 5W.
- PCT MA2-M is working with Ambit cable modem
- I have the Radio Shack amp. It's the one with 4 outputs and and amplifier. It works fine with my Comcast cable modem and Tmobile@Home VOIP service.
- picked up a philips amp from walmart provides 18dB forward amp of 54-1000MHz return path 5-42 mhz. works well, single line amp.
- Please add the RCA - Digital 4-Way Bidirectional RF Amplifier
Model: DT140M, Its a four way splitter and Amplifier. Purchased at Best Buy for under $40.00. Works great. Boosted my Cable Modem and no more black outs. Fishmoss
- Walmart carries the Philips 4-Way splitter that is Amplifier powered, it says Bandwidth 50-900mhz, Gain 12db, response 1dB, but after I bought it hoping to return it if it didnt work i noticed the big black box "not for use with cable modems or digital cable boxes" (the 2 things i need at the end of my line) Anyway i waited too long so Im stuck with it, but I can tell you it doesnt work with cable modems but is sold as an amplifier/4-way splitter
- thanks guyz 4 info on these booster amps
- After years and three cable modems/8yrs, I decided to check my download and upload power and S/N. These were out of range but against advice I purchased a Radio Shack 1 to 4 Bidirectional Amp (Catalog #: 15-2506) It has an adjustable output, so I was able to "tune it" to the ideal S/N and power levels. There has not been a modem dropout and the speeds are stable as well as the fact I can have a TV hookup in the same room. Great product, read the customer reviews about the amp at Radio Shack.com! (4.5 stars out of 5- 20 reviews)
