Some of you have been asking for this for a long time. And now it is finally here! A 5W VHF TV transmitter is your ticket into the world of TV. Build your own TV studio and broadcast your own TV program! Transmit movies from your PC to your living room, re-transmit the TV program you've never been able to receive in your valley, run a college TV station, cover rural areas of Africa with TV signal from satellite stations, run a hotel cable system info pages or just have fun... this unit will keep you busy during the cold winter evenings and is sure to provide lots of fun for many months to come!
Unit is available as a populated and tested board or a rack-mounted ready-to-use transmitted. Rack mounted unit runs from 12-15V DC, solar panels, car battery or mains voltage (with power adapter). Optional stereo encoder board will be available shortly and will plug into the main transmitter board to provide stereo sound and DSP processing. Up to 3W of output power offers from several hundred meters up to about 5km of range depending on antenna type used on transmitting and receiving side. High-gain yagi antennas on both sides might offer even more range in
favorable conditions.
Unit is rugged and comes with SWR protection, made for 24/7/365 operation. Each unit has a wide-angle high contrast backlit LCD display. Output power and channel can be adjusted with internal trimmer.

- This add-on card enables stereo sound, it was designed for NTSC system, used in USA and most of South/North America.
Antenna options
We have provided several antenna options for you, they are with one exception suitable for the high VHF band (175-225MHz) and they both come with 5 meters of coaxial cable with installed connectors:
- The VHF HI GP antenna (175-225MHz) is suitable for transmission in all directions (omnidirectional) and is very compact, offers slightly less gain than a dipole.
- The VHF LO GP antenna (66-88MHz) is suitable for transmission in all directions (omnidirectional) and is very compact, offers slightly less gain than a dipole.
- The VHF HI dipole antenna (108-195MHz) is suitable for transmission in all directions (omnidirectional) and comes with a tuning chart, offers 2.14 dBi gain
- The 3/4 wave exterminator TV VHF HI antenna is omnidirectional and is suitable for transmission to multiple receivers around the transmitter site. We will tune it for you so you have to specify TV channel at time of ordering. This antenna has the highest gain of the lot. Please re-check SWR after installing this antenna as some difference in tuning can result during transport.
