Commercial VHF PA…

[BMDaug]

Hey everyone, I’m looking for a good mobile oriented PA that covers at least 150-174MHz. I’m looking for something that’ll take an input of about a watt, and output something between five and ten watts, so nothing massive.

Thanks for reading!

VHF amplifiers have narrow windows. Don't expect efficiency from a 24 MHz window. Plus, wideband expectations from a mobile antenna will be a problem.

TPL had a series of wide band amps.

TPL had a series of wide band amps.

I already know what the final response will be. Engineering and money talks.

Thanks! I found one on eBay for about $60. It’s exactly what I need! 1W in, 10W out 136-174MHz.

@n1ofj ya, the ham stuff especially is very narrow, but my antennas for commercial are all 136-174 and most of them are also 380-520 and 762-870! I need those for my Harris XG100Ms.

This particular PA will be for my Pyramid SVR-250 setup on one of the 100Ms. It’ll crossband to the trunking network or inband repeat to my Tait TB9100.

@prcguy Thanks again!!!

Just make sure its the wide band version that will cove all that without tuning. Many TPL amps are stamped 136-174 but are tuned for maybe 5Mhz of band width and if you move frequency you need to retune. I forget what series the wide band was called.

Thanks! The manual I found says 136-175 with no tuning so I thin I’m good! This seems like a smokin deal! The guy has a quantity available too!!

Edit: these are NIB too.

I’ll admit I really lucked out this time! I’m sure the price new was quite a bit more than $60, but dang, NIB for $62 shipped is almost as good as free! This project is gonna rock now. The 2W that the pyramid offers felt weak to me and now I can run the pyramid at 50% and still get 10W out of the PA… I like low stress!
