Coaxial receiver relay connections for people who want to be more like the rest of us. I mean, whatever. Just let it go.

I had a chance to take a look at a receiver relay, and it is important to connect the antenna coax to the relay in the right direction. The coax has to be connected so that the DC voltage on the center conductor will not be applied to the receive antenna. This can damage or destroy some radios, or reduce the life of devices like semiconductors and relays.

This should be obvious, but I did not think about it until I saw it in an old ARRL book today. If you hook up your coax wrong, this can cause receivers to malfunction. This can occur during transmit-receive switching if there is DC present on the coax, so it applies to any station that uses DC on the coax for keying, including most rigs with VOX and SSB rigs.

A receiver relay is a magnetically operated switch that is used in the receive antenna of the receiver. The receiver relay has a set of contacts that are moved by the magnetic coil to switch between two antennas.

One of the most common uses for a receiver relay is to connect a single receive antenna to two receivers. If you have two receivers, you can use a coax switch to connect them both to the same receive antenna and then use a coaxial cable with an electrical contact on each end to make a simple connection between the two receivers.

In this case, you will have to have at least one receiver relay connected to each of your receivers. You will also need a coaxial cable with an electrical contact on each end, so that you can connect the two receivers together.

If you want to connect your receive antenna to three or more receivers, then you will need more than one receiver relay. In this case, you will also need more than one coaxial cable with an electrical contact on each end, so that you can connect all of your receivers together.

Here are some pictures of a coax relay that I built. I use it as a receiver relay for my remote RX system.

I used a K1EL WinKeyer PCB and mounted it in a Hammond 1455R1201 ABS plastic enclosure. There are holes on the sides of the box that can accept SMA connectors, but since I wanted to use RG-6U coax, I had to drill out the holes to accept bigger connectors. I drilled out two holes on each side of the box so that I could mount two relays inside.

I used an RCA Jack/Plug set with a SO-239 adapter on one end and an RCA plug on the other end. This way, I could connect the coax cable directly to the box without having to build any adapters. The jack/plug set was obtained from Radio Shack for about $4.

It is possible to buy pre-fabricated coax relays from DX Engineering but they are much more expensive than what it would cost to build one yourself. Another option would be to buy one of these pre-made boxes from DX Engineering, tear apart the circuit board that is inside and make your own custom box.

You can use the receiver relay to connect your outdoor antenna directly to the receiver, eliminating a power inserter and an additional cable drop.

I’m not a big fan of the receiver relay, but it’s sometimes useful. If you have only one receiver or DVR, and your outdoor antenna is close enough to the receiver location, you can use this to connect your outdoor antenna directly to the receiver, without using a power inserter and without having a separate cable drop for that one receiver. This eliminates all sorts of potential problems with grounding and power inserters, but it does require the coax from the antenna be in the same room as your television.

If you are going to use this method, I recommend using an amplified splitter. It will give you better performance than a non-amplified splitter, and it will prevent RF overload from signals on other channels from affecting reception on channel 53 (the channel used by most receivers for communication with the dish).

This article describes how to set up a single tuner HDTV system with just two cables: one carrying satellite signals from the dish to an amplified splitter, and another carrying signals from the splitter to your TV or DVR.

The receiver relay is a common component of many audio and video circuits. They are often used in multi-speaker systems to switch between speakers, or in surround sound systems for switching between inputs. A relay consists of an electromagnet, which is activated by a small electrical current. When the magnet is activated, it closes a set of contacts which completes an electrical circuit. This can be used to turn on and off other components such as speakers or amplifiers. Relays can also be used to protect sensitive equipment such as microphones from phantom power, or they can be used to create a delay before turning on power to equipment such as TV’s, which prevents the audible “pop” that occurs when turning on equipment with no load. In addition, relays can be used as a safety measure in cases where there is a potential for damage to electronics due to voltage spikes or other causes; if either of these occur, the relay will open its contacts and prevent the voltage from reaching the electronics.

The receiver relay is commonly used in conjunction with a coaxial cable because it allows for easy connection to the rest of the circuit without having to solder connections directly onto the receiver itself. While soldering can be done directly onto the receiver, it is not recommended because it makes replacing components
