High Power FET Mobile Amp

[Unit 148]

Does anyone know of a higher power 12v FET amp than the Palomar 450?

Links or photo's appreciated.

I'm in the market for something with a bit more grunt.

Thanks.

Mosfets have not really caught on for illegal 11m use here in the USA. Most decent amps are still running 2879's, 2290's or 1446 finals.

If your really in the market for a quality built amplifier then there are several at this site. Here is one link as an example.

And here is a link for more of the outlaw 11m amplifiers. A 450 model is the largest they make however.

I am not a big fan of mosfet anything really but that's what we are stuck with now for radio's.

A local here has the ALS600 with 10 metres. It sure works great.
edit to add: I ran the MF200 for a spell and it wasn't bad, nothing compared to 2879 pilled amp but still did the job well.

Hi Guys,

I did state in my original post 12v.

I'm not too sure I'd get much out of a big 50v LDMOS from a 12v rail!

I did think about powering a 50v PA with one of these rascals:

battery chargers, fuel cell converters - SU13 Step Up DC/DC Converter Listings - Zahn Electronics, Inc. Products

Geoff,

Your man does not list any FET amps!

Re Superior Amps, are they built by John Denver?

I've followed all the past posts and You Tube videos on these amp's from the early days.

It does seem at the very least that the internal wiring's been tidied up somewhat!

In one of his videos it states requiring a driver of around 100w, is that carrier or pep?

Has anyone independent of the manufacturer measured the pep output of the 16-FET box?

Do you think one can see a reasonably clean 1kW+ pep out of it?

Does Superior Amp's / JD have a website?

Someone please feel free to pass on my e-mail and get him to mail me:

info@transmittersrus.com

I'm in London, England but have an address in Vacaville, CA if the guy does not want to ship International.

didnt you watch the video??

if you cant reach him pm me and i will ask for his email addy or phone number .says he has some ready to ship out .i guess he is friends with the builder .

Looks pretty decent but I did not see any mosfets which is what he is looking for.

Thanks for his PayPal ID!

Geoff,

They may not be RF mosfets but FET's they are.

Out of interest I wonder what if any other similar high power CB/11m FEt amp's are out there.

Thanks anyway.

were you able to reach him?if not i will ask for his official email but i am pretty sure its the same as his paypal id .
those amps are tempting thats for sure .high peak watts with a low amperage draw ,great for guys without alot of amps under the hood .
you can catch john denver on ch28 when skip is rolling usually talking on the mosfet box ,chances are you already heard it and didnt even know .

"Mosfet" is a dirty word in my house.

Skywalker has a 700w FET amp for $275

Sky-Fet 600M - $275.95 : skywalker electronics, Your one stop shop


I have been running a palomar 450 FET LD with my 2510 in the pick up for almost a year and for the price per watts it was a good deal it pushes 500 watts, they do run hot so I added a 120mm fan and problem was solved!

Hi FNKY,

No response from him at his PayPal address so would appreciate it if you can find a direct e-mail address for me.

Feel free to pm me if you prefer.

Tin Can,

Do you gave any idea which four FET's are in the output of that Sky Fet 600 as if the same as the Palomar then they may be stretching the numbers somewhat!

Psyco,

Sorry you don't like FET's in the house but with ever increasing voltages being used on these RF devices I'm afraid it's the future, like it or not

Thanks.
