Extend Range

to the antenna

Mine doesn't have a short wire coming out of it. At what component Resister or cap would it be.

transmitter?

is there an f connector on that unit?

The length of the antenna has to be the correct length for the wavelength of the transmitter...I agree...if he can find the rigid whip antenna for the Linear transmitter that would be the way to go. And even still..the range gain may be minimal.

This unit is that old and no fittings

Rich,

Simply adding wire to an antenna doesn't necessarily improve the performance of the transmitter, most of the time it will take the antenna circuit out of resonance and degrade performance... Contact Linear's tech support before making any changes........... Good Luck, Russ

I noticed a cut jumper in mine. But cant find any reason for it The web page shows no jumper to cut for any reason of setting a delay.

wavelength in meters = 300 / frequency in MHz

A 433 MHz transmitter has a wavelength of .6928406 meters, or 27.270206 inches. You HAM guys can check my math, but theoretically, you could make a quarter-wave antenna of approx. 6.82 inches.

The antenna has to be a specific, exact length which is inversely proportional to the frequency of the transmitter. You may use half or quarter-wave antennas though. js

AND if you ran that out a few more feet...you could just run a wire to the door/window.

or slap a 500 watt linear amplifier and a nice beam antenna on that baby and yer all set.

You have to use a Belgian Balun Babbelator Adapter Device (BBBAD) to get it to work.

OK whare in the little transitter do you place it? Where on the circuit bord dos it go?

What would happen if I add a longer wire to the receiver?

I could run a piece of coax 20 ft to the edge of the room shorting up the transmitting distance.

if you use twice the length you have yourself a 1/2 wave antenna..

anything between and you have a un tuned antenna witch is usually worst then no antenna

if you don't have the matching coax for the line you will have a bad signal..

if the transmitter was balanced to transmit on a 300 ohms line and you put a
