How do I hook up a 75 ohm cable to the unit?

INSTALLATION

Channel Master by PCT indoor antennas are designed to provide optimum reception of

UHF / VHF and FM signals. These antennas have 75 ohm outputs, which allow simple,

hassle-free connections to today's newer TV sets that have 75 ohm F type connector

inputs.

Simply attach one end of the supplied 6' cable with F connectors to the output of the

antenna (Fig.1). Attach the other end of the cable to the input of the TV set or VCR

(Fig. 2). Some adjustment of the antenna might be necessary for optimum viewing.

Model CM-4030 includes a built-in amplifier and separate power supply.

1. Follow the same steps as above for antenna to TV / VCR hookup. Note : Model

CM-4030 also allows for two set / VCR hookups with its unique dual output feature.

2. Insert the power injector into the back of the antenna (Fig. 3). Plug in the power
transformer to the closest electrical outlet (Fig. 4).

Radio Shack has an
adapter catalog number 278-0291. It takes some effort to push the 278-0291
adapter onto the FM UNBL 75 ohm terminal so wait until you have the 278-0291
installed before you connect your 75 ohm coax on to your new adapter.

This will resolve your FM screw on F connector antenna interface issue.


I see others trying to
help suggest using a 300 ohm to 75 ohm transformer match unit, this isn't what is needed. Your receiver antenna input IS a 75
ohm input.

I would imagine the level is too high. Does your loop amplifier not have a sensitivity control?
You could come out of the scart socket but check for a headphone volume control first!

The connection standard requires that the pins are utilised in the following manner:

Hope this is useful.

A 21 pin SCART cable with all pins connected is wired as per the following diagram:

The power cord is the antenna and it should be stretched out straight for best possible reception. You could experiment with re-orienting the Bose, too.

There is a threaded 75-ohm coaxial FM External connector. You could probably get a compatible FM antenna at an electronics store.

See the manual, Page 10

External FM antennas can be had for as little as $7 for the a simple dipole version (looks like a "T") to a highly directional outdoor type for over $150 at your local Radio Shack below:

The simple $7 dipole is a "twin lead" 300 ohm type that many home stereos shipped with because they are inexpensive, take up little room in the box and work surprisingly well for all but the very distant of stations. These antennas are also found for sale in many department and some hardware stores too. Your stereo may not offer twin lead or 300 ohm hook ups (2 terminal screws near the ANT label) but only a 75 ohm connection (like your cable tv connections), in which case, you'll need an inexpensive 300 to 75 (terminal to cable) ohm balun (or matching transformer) like this one below:

or to go the other way - from 75 to 300 (cable to terminal) ohm balun like this one:

Because your TV is an older one, it might not have, what they call RCA inputs (the 3 colored cable) Red-audio right, White-audio left, Yellow-video. If I understand you.

You do have the option of using the 75-ohm coaxial cable inputs. Signal comes in from outside to the 722k, Output of the 722k to the 75ohm coax input on the back of the TV. Tune your TV to ch. 3 or 4. Make sure the switch on the back of the 722k is set to the same.

If you really want to use the RCA colored cables, then you need to buy an RF modulator, which integrates older tv's to newer products. But usually dvd players, not necessarily cable boxes, but it would work if hooked up correctly.

You plug the RCA red, white and yellow from the 722k, into the rf modulator, choose channel 3 or 4 on the modulator

Connect 75ohm coax cable from rf modulator to TV 75ohm coax cable input. Choose channel 3 or 4 on the TV.

Hope this helps.

what connectors do i need to splice coax 3c-2v-75ohm that came with hdtv antenna dog chewed into it

Nonsense. FM is included in MOST tv cable subscriptions- make sure your subscription includes this service. Do you have another receiver/tuner to test with?
Check all the connections between the cable entrance and your tuner; eliminate all splitters for testing. If you can get another tuner to work on your cable, it may be time to check into your tuner-
There is no difference in signal level between tv and fm- your receiver is not gonna burn up! If it has a 75-ohm cable input, use it!

There was a black wire included (with a metal "cap" to insert in the FM center connector) that served as the FM antenna, but in a pinch any wire can do, preferably about 33" long and with the insulation stripped from the last inch or so (or get creative and sand the last inch of varnish off a properly sized untwisted clothes hanger and gently bend to suit). Bare stranded wire should be twisted or folded until it's thick enough to firmly fit the middle "hole" of the FM antenna connector. Be careful that no strands of wire short to the metal ground "ring" surrounding the hole or the antenna won't work (although it won't burn out your amp like shorting the speaker wires would, it just won't work). Orient the wire horizontally or vertically for best reception. This unit also doesn't pick up FM very well if you're in a steel-framed building or away from windows in the general direction of the local transmitters, so moving the unit closer to a window may help dramatically. In bad reception areas you can get an external FM "rabbit ears" type antenna but you'll need the "European" style of 300 ohm to 75 ohm transformer to plug it into the unit's FM connector (one that has a bigger central connector "plug" than the usual US units). Some cable systems also still support FM, if yours does, a VHF/UHF/FM signal splitter and either the above mentioned transformer attached to flat 300 ohm cable or a plain  "European" style connector attached to the end of the 75 ohm round black cable will do the trick. Some Radio Shacks have them. Good luck!

What type of antenna is this. You will need 75ohm cable for this with good 75 ohm 3 way splitter. Please be sure that TV cable is not going to work.
