Radio Frequency-Reducing Products

Network Adapter

A network adapter allows you to bring Internet into a room that is not near a router and use your Ethernet cable to connect to the Net without using Wi-Fi (don't forget to turn off the Wi-Fi on your computer)

TP-LINK AV1200 Powerline Adapter, Gigabit w/ Power Outlet Pass-through Adapter Kit.


MOCA unit

Another choice to send Ethernet over wires is to use a MOCA unit, from the Multimedia Over Cable Alliance. This uses your house's existing coaxial cable network, normally used for TV, to send Internet from the room with the router to any other room in the house that has a working coaxial cable. That cable must be networked with the one in the room with the router. You can use a coaxial cable splitter to send data to a TV as well as sending Internet data between rooms. Coaxial cable is shielded so there should be no dirty electricity (at least not the electric field component). Therefore, those with electrical sensitivity should do okay with this technology, but we always suggest that you try it to make sure.

Here are two choices:

Actiontec Ethernet over Coax Adapter Kit

You can buy additional single units of the Actiontec MOCA unit by clicking here or on the image below.

Here is another choice for a MOCA unit: Legrand DA2204V1 Four Port Coax Network Adapter


Ethernet Cables

A large selection of Ethernet cables are available here.


Adapters for Macbook to Ethernet

Connect an Ethernet cable to your thin Macbook laptop with either of these two adapters. Macbooks do not have an Ethernet port like older, thicker Mac and PC laptops do.

Thunderbolt-to-Ethernet Adapter

USB-to-Ethernet Adapter


Adapter for Mac Laptop to Ground the AC Power Cord

Mac laptop AC power cords that use the two-pronged adapter with the two blades that swing out will produce high AC electric field EMFs when you touch the laptop. This adapter is plugged into one corner of the white in-line transformer box so you can plug the transformer box directly into a surge protector or wall AC outlet.

To avoid this, you need the cord that came in the box with the laptop (at least up until recently) with the three-pronged plug at the end. Pull the two-pronged adapter off the white transformer box (and throw it away). Slide the end of the grounded AC power cord onto the corner of the white transformer box where the adapter slid off of, and now your Mac laptop is grounded. You won't get tired anymore when working on your laptop like you might have before when it was ungrounded.

If your Mac laptop did not come with this grounded cord or you have lost it, you can order one from Amazon here:

6 Feet AC Power Adapter Extension Wall Cord for Apple Macbook/Pro/Air/Mini (US 3 prong)

Modem without Wi-Fi

Here are two choices for a modem that does not have Wi-Fi. It doesn't have a router inside of it, either, so you will need to purchase a separate router, such as one of the models listed below. These modems are approved by Time Warner, Cox, Comcast and perhaps other companies. Purchasing one of these modems means you don't have to pay the cable company the monthly fee to rent the modem they give you.

To purchase a grounded AC power cord for an iMac or a Mac or PC desktop central porcessing unit (CPU or tower), go to Safe Living Technologies. These shielded cords will also fit onto a PC laptop in-line transformer box that will accommodate the special plug at the end of this cord that goes into the computer. This is also a solution for PC or Mac monitors and printers that have an ungrounded AC power cord (that will accommodate the special plug). The shielded cords from Safe Living Technologies come in six and twelve foot lengths. Order here. (Use coupon code CHHOM when ordering).


Router without Wi-Fi

Here is a router that does not contain Wi-Fi. It only sends Internet using Ethernet cables, over a so-called hardwired "Local Area Network" or LAN. Up to four devices can be plugged in to this model.

Trendnet TW100-S4W1CA 4-Port Broadband Router


Routers with Wi-Fi switch

Here are two models of routers that have Wi-Fi with a switch to turn that Wi-Fi on and off:

Netgear N600 Dual Band Wi-Fi Router, model WNDR3400 The Wi-Fi on/off switch is on the back of this model.

TP-LINK TL-WR1042ND The Wi-Fi on/off switch is on the front of this model.


Cable Modem that Supports both Internet and Telephone (without Wi-Fi)

Here is a modem that provides both Interent and telephone service from the cable company without Wi-Fi (check with your cable company to make sure they support this product):

Arris TM822g DOCSIS 3.0 Telephony Cable Modem


Ethernet Switch

When you have more than one device in the same room that needs Internet service, such as two computers, you will need an Ethernet Switch, also known as a Hub. Plug the Ethernet cable from the wall jack or Network adapter into this Switch, and then you have four ports to plug Ethernet cables into. This unit does not transmit Wi-Fi.

TP-Link TL-SG105 5-port Gigabit Ethernet Desktop Switch


Blu-ray Player for Internet TV without Wi-Fi

This unit provides Internet-based TV (Netflix, Hulu, YouTube) to your TV set in a hardwired way. Plug an Ethernet cable into the Blu-ray player and an HDMI cable from the player to your TV set.

Then access the Blu-ray control settings using the on-screen prompts on your TV set. Go to Network and choose Hardwired. I have verified with my RF meter that the Wi-Fi signal from the Blu-ray player is successfully turned off.

Corded Telephones

You can purchase from a variety of corded telephone models available from Amazon by clicking here. Be aware that not all models listed on that page are completely cordless. In fact, always be sure to avoid a model that also has a cordless unit in the box, as that means that besides having a corded handset, it also has a radio frequency transmitter inside the base unit.


Safer Baby Monitors and Security Cameras

The first option to reduce potentially harmful radio frequency EMFs at the crib (and near the monitor that Mom has near her) or to avoid radio frequencies from a security camera is to use a D-Link Wireless HD Day/Night Network Surveillance Camera. The Wi-Fi shuts off when you plug in an Ethernet cable. You will need to order a pair of Network Adapters, listed above, or run Ethernet cable to your baby's bedroom or to the security camera to connect to your router and to the D-Link website.

Then go to the secure D-Link website on any laptop to see and hear your baby without any radio frequency EMFs near the crib. Be sure to also use an Ethernet cable to your laptop and turn off the Wi-Fi on the computer.

D-Link Wireless HD Day/Night Network Surveillance Camera


The SmartNOVA Baby Monitor is a cordless camera and microphone that sends its signal wirelessly. However, the manufacturer is aware of EMFs and has set the signal strength very low. It is relatively safe at six feet and beyond. I would not recommend putting this monitor closer than six feet from the crib, or from Mom.

You can order the SmartNOVA Baby Monitor from Bellyarmor by clicking here.

Clamp Meter

The Triplett 9200A Clamp Meter allows you to measure current on metal grounding paths, such as water pipes and TV cables. You will also be able to measure individual conductors within circuits, such as the hot, neutral and ground wire, as well as measure for net current on the whole circuit. This small clamp meter allows you to get into tight spaces, such as inside junction boxes and breaker panels.

Remote Electric Outlet Shut-Off Switch

The Etekcity Wireless Remote Control Electrical Outlet Switch for Household Appliances, also known as the Zap Wireless Remote Control Switch, allows you to remotely shut off an electric appliance that is plugged into a hard to reach outlet. This eliminates voltage in plastic AC power cords to bedside lamps and other appliances within six to eight feet of where you sleep. Use to shut off the lamps at the outlet without having to reach down to a plugged-in switch. The following item provides one Zap remote controlled plug.

Etekcity Wireless Remote Control Electrical Outlet Switch

Etekcity also makes a package that contains three Zap remote-controlled plugs that you then control from one bedside remote. There will be a different button for each Zap plug.

Manual Electric Outlet Shut-Off Switches

You can use a plug-in switch at outlets, if you can reach them, to eliminate voltage in plastic AC power cords to bedside lamps and other appliances within six to eight feet of where you sleep. Leave the lamp switch on and turn off the light at the outlet using a plug-in switch. You will have to reach down to the outlet to manually shut off the switch and lamp each night. These are available at local hardware stores or from Amazon at:

Leviton Plug-in Switch Tap


If you need a grounded, three-pronged shut-off switch, you can order one of the following items:
