    Many thanks for your advice. Unfortunately cabling is not an option, however, the AV transmitter sounds like an ideal solution.

The correct way to get TV to the room with no antenna is to run a cable from the room with the antenna to the room with out. You just need to put a splitter on the antenna cable before it goes to the TV.

Or you can do it wireless with a device called a wireless A/V transmitter. On a small scale, it works the same way as a TV antenna only instead of a local broadcast station sending a signal out to anyone who has an antenna, the TV in your antenna room will be the sender of the signal for the receiver in your antenna-less bedroom.

The way it works is connect the television with the antenna to the transmitter, and the TV in the room without antenna to the receiver. The signal travels through the open air, and is decoded by the receiver in the bedroom. My advice is to have the transmitter and receiver in as open a space as possible to avoid any interference.

A company called Terk makes one called the LF-30S. While I haven't used a wireless A/V transmitter, I did use a wireless camera on many occasion's. The signal wasn't as good as if it were hard-wired, but it still looked pretty good. I imagine much the same with this product.

Just bought the MOTOTOROLA MR355R can't transmit beyond 1/2 mile, no transmitting signal, PLEASE HELP


A few things to check, and some facts about 2-way radio range:

1) Be certain you are using a fully charged battery.
2) Hold your radio upright perpendicular to the ground (antenna straight up) for the best range. Tilting the radio can reduce range significantly.
3) Face the direction you are wanting to transmit.
4) Wear the radio up high on your body. Height and placement of the radio determines range.
5) Double check you have the radios programmed to the exact same frequency and code. Sometimes on a "near" frequency you can transmit to another radio on a different frequency, but it would be poor and short distanced.

Facts:
2-way radios are line-of-sight communications. Anything you place between the two radios will reduce your range. Outside radio-to-radio in a flat area you should be able to talk up to 2-miles line-of-sight. If you were on a mountain you might be able to talk miles and miles into the valley below. (You can talk as far as you can see in most cases.) If you go inside a building and try to talk from inside to outside you might only get 1/4 to 1/2 mi. Your range will vary according to your circumstances/location.

Most TalkAbout radios are 1/2 watt radios and by comparison business radios are up to 4-5 watts, with some being aided by repeater/trunking systems which would enhance the overall range.

Best regards.

My out door TV antenna stopped receiving 1 of 8 channels, this station is 20 miles away, the station said they weren't having any problems transmitting, do I need to replace the ohms device?


Is the antenna digital? If not its analog. Most stations are going to digital HD and dropping analog. The other 7 are still broadcasting analog. Ask station if they are still broadcasting analog if antenna is digital. If no, do a rescan of stations in menu of tv. Let me know.

Gosting image


Hello
Ghost image, otherwise called multiple images, that seen as duplicate one next to the picture, normally left side, are mainly due to the reflections of TV signals. That is two signals of the same object, but different in amplitude and in direction comes to the antena of the TV. Both of them gets processed by the internal circuits of the telivison, and comes as images on the screen. The first strong signal will produce strong image, and following will get to the next of it. Due to, say if a news reader appears on the screen will have a shade of the image very next to it, which is annoying.
The only remedy is to prevent the reflected image that comes to the antenna. Tv signals are transmitted in a techniqe called Horizontal Polarisation. That is, signals send from the transmitting tower comes to your antenna, in such a way that to a snake travels on a plane land. On the way if there is an obstruction, it will be delayed, if there is any high rise bulilding or so behind the way of its path that is some distance far away from your antenna or just behind the antenna and transmitter, that high rise structure will reflect the transmitted waves back to your antenna, which causes Ghost image to be produced.
You just reorient your antenna in suach a way that there will be no reflection signals comes to it, and the orginal transmitted signal from the tower only reach to it. You may have to repoition it or have to hoist higher or so. It is a trial and error method, while watching picture on your TV.
I advice you so, thinking that nobody has realigned the video If stage circutary inside your TV. If anybody has done so without proper testing and aligning equipment, this fault may occur. OK.

Cant get a full signal because man next dor is a radio ham and blocks our signal wot can we do we have boosters and new arial


Unless you are in channel 2 (does not apply to USA any more) and he is transmitting on 10 or 11 meters,you may get some interference. If he is not transmitting, there is no way he can block your signal to the TV. Make sure all your connections from the antenna to the tv are ok,or try directing your antenna to another channel(location). Unless you live to far from the area where the majority of stations are,try with a smaller antenna close to the tv to make sure you have everything connected accordingly. We ham radio guys normally are very friendly if he is a ham radio guy (not a CBr) I am positive he will help.

Just bought a cobra 148 gtl dx cant get a antenna outside just wondering the best indoor antenna i could use thanx


There really is no good indoor antenna.

You need to understand how the radio works and what reflections is.

Your radio radiates RF energy from the antenna. If the antenna is not the correct length for the frequency you are transmitting on then the signal will be reflected back into the radio and burn up the final transistor which is the lifeblood of the radio. This is your SWR or standing wave ratio.

The antenna has adjustments to correct this, and it is a simple process.

Here is what will cause you trouble. When you measure SWR in a car, you do it in an open lot, and not in a closed in area, because structures such as trees and buildings can cause reflection as well. If you inside a garage, then you will get a lot of reflection.

Beings you will be inside with the antenna, you are trapping the RF in a room, and it is reflecting most of the RF. Your SWR's will be really high, and hurt the radio.

Indoor antenna's are made so that it compensates for this, but your signal will be very weak, and your receive will be garbage.

Here is something you can do to get the antenna outside.

First get a real base antenna, like an antron 99, its good for the money.

Get 2 lengths of galvanized pipe 2" by 10 foot and a 1/4 inch thick steal plate. weld the pipe to the plate so that it will stand off it. Make sure its all the way off to side. connect the 2 pipes together, put the antenna on the end of it, and stand it up. Park the wheel of a car or truck on the plate. This will stabilize the pole.

Now you have a temp antenna tower you can take down and put back up easy.

I wouldn't go higher then 20 feet.

Guide plus on my rca p52937 tv


You are right, the Guide Plus is transmitted to your tv over the air. If you have a cable company supplying your programs, your Guide Plus will not receive a signal to set up. You will need to get a two-way splitter. It has two connections on one side and one on the other. The side that has one connection goes to your tv. The side that has two connections will connect to your cable supplier and the other to a rabbit ear or outside antenna. Then the tv has to be off over night to restore your Guide Plus.

No signal converter box.


Why is this in the computer section?

Anyway, don't exchange the box just yet! First, can you access the converter's menu? Because mine automatically comes up with the "no signal, call customer service" message, but I can access the menu fine -- so the hook-up is not the problem. If you can access the menu, let it autosearch for you, because mine can't be used until I do this. If you get the "weak antenna signal message", refer to the user manual to find out how to check your antenna signal strength; if it's in the weak range, you have to buy a better antenna, most likely from the official source: http://www.accessHD.tv

You can always exchange the box and repeat the process. Getting the "no signal" message is a good indicator that you've hooked everything up right, especially if it's accompanied by a customer service number. You can email me at kalalkb@gmail.com and I'll try to help you troubleshoot the problem if you like. I'm up all night.
