Muy buena la prueba, Pregunto. Cuando una antena falla o hay un cortocircuito generalmente es constante o permanente, cuanto tiempo puede aguantar en cto cto permanente.
You will damage the transistor if you hold the short, try disconnecting the antenna or dummy load as that will smoke it. 1000watts into 50ohms Is a awful lot of power, the amps cost over $500 usd not that cheap either. The wire is held with pliers is not a short circuit, but it causing a mismatch. It looks like about 100 watts of rf energy in those sparks you are pulling. If you disconnect the load and mess with it, it will flash up and burn and destroy the rf connector, catch fire. VHF at 1kw is no toy it can be dangerous.
I have a 500 watt rf amp pallet with mosfet include and a 500 watt power supply to power the rf amp pallet and its connected to a 5watt fm transmitter.With these items will it work for a fm radio station?
here you go son. board: www.ebay.com.au/itm/1-2-KW-LDMOS-power-amplifier-1-8-54MHz-HF-for-BLF188XR/253578807456 Mosfet: www.ebay.com.au/itm/1PC-BLF188XR-high-frequency-tube-microwave-tube-RF-communication-module-V2767CH/292683862355
These Fets are ALMOST unbreakable, BUT, as others have said, leave it into an infinite VSWR for some time, it will not survive. In addition, a near lightning strike to the transmitter will kill ANY MOSFET.
Its a good idea to run the amp at less than 1/2 power for the purpose of increasing its life and reducing the chance of damage if a mismatch occurs. Use more modules to get the power needed, instead if possible.
isso nao e verdade um trasitor nao aguenta esse curto que vc provoca esse transistor vc nao vende e fabricado pra aguentar isso mas o de venda deus u livre de fazer isso ai e truque ok sou tecnico de rf mas deus te abrace tchallll
An amplifier that doubles as an arc welder!

EXELENTE ..BUENA PRUEBA....TRANSITOR DE CALIDAD
Have you tried to connect without antenna or load?
Игрушку нашёл. Искры понравились.
Kalau prodak rf kit udah jelas ok ..jeepri garut
Try holding the short for a few seconds, then I bet that transistor will no longer be unbreakable!
nice to see meter when shorting out
ronniezzzz you can
Mantap mas jeepri garut hadir
Muy buena explicación gracias
Blf188xr is top!
Man you are crazy!!!
Hola amigo donde se compra una de esas tarjeta de 1000 w
HOLA DONDE CONSIGO EL MODULO COMPLETO Y CON LA FUENTE SOY DE CALI COLOMBIA -------------
But how long would it last without an antenna?

I'm in love
En Argentina donde lo compro
HELLO! ,,, WOULD LIKE TO KNOW IF THE BLF188XR CAN WORK WITH 20VOLTS.
THANKS.
How many watts does the fm transmitter have to be to work with your 1000 watts amp pallet
The datasheet for the BLF188XR shows a max 40dbm input power which is 10 watts.
Nice setup..
I've blown up two MRF186 on the same 2m amp project and have yet to know what I'm doing wrong, maybe I need this one instead?
Yes me too. I bought one off of Ebay from China and it is so delicate that if you do so much as breathe on it a certain way it will blow.
What input power do you need to drive this amplifier to 1 kW output?
@Alexander Kalish Thats all? I have never heard of a device with that much gain. That is nearly 30db of gain in a single device.
Will it work on a.m. how much for the kit
Mas ini rfkit yang dislawi bkn
nice welder.
Nice 👍
lo que no veo en tu vídeo es la luz roja que tiene la placa cuando enciende la cual es bastante brillante como para que no se vea..
Where are the other 5?
Hola tengo una placa similar a esa pero no consigo que me de los 1000w solo me da 600w con 3,5w de entrada y 48v que puede estar mal saludos..
you need 50 volts and 5 watts power in.
estemado amigo soy Asencio cruz desde ancash como nos contactamos con usted quiero una emisora
Scusi volevo chiedervi se sa che vernice e' il rivestimento interno del coperchio
What is the prizes of the this amplifier.
100? watt
Which is using the power input?
I have a 500 watt rf amp pallet with mosfet include and a 500 watt power supply to power the rf amp pallet and its connected to a 5watt fm transmitter.With these items will it work for a fm radio station?
It will work but you won't get full power as you will need a more powerful PSU. PAs are not 100% efficient.
I left many messages to be able to buy this pallet and they never reply
1000 watt spark-gap transmitter.
como consigo uno con quien me pongo en contacto
nesecito un mref6vp6300h .Como conseguirlo?
Oi ficou legal mim mande esquema
hola amigo, como hacer para adquirir 1000w FM amplifier pallet?
please contact sales@rf-kit.com to get this pallet
hola pudo contactar a estos vendedores saludos

you can almost use this for welding, but not for too long!
A conductor of almost 1/8 wave length is not really a short circuit
Yes. The same trick a quarter wavelenght further down the line, would put a high voltage peak on the LDMOS drain destroying it immediately
Its a good idea to run the amp at less than 1/2 power for the purpose of increasing its life and reducing the chance of damage if a mismatch occurs. Use more modules to get the power needed, instead if possible.
i want one
oww..
because of the length of your wand that you do not make a real short circuit because of the wavelength
isso nao e verdade um trasitor nao aguenta esse curto que vc provoca esse transistor vc nao vende e fabricado pra aguentar isso mas o de venda deus u livre de fazer isso ai e truque ok sou tecnico de rf mas deus te abrace tchallll
wow 1kw big as chocolate bar, and do not do that Short-Circuit yet
