Re: UHF Repeater Input Frequency Issues
A preselector is simply a band pass filter. A splitter is….. a splitter. Matt AL0R Sent: Thursday, April 3, 2025 18:21 To: [email protected] Subject: Re: [repeater-builder] UHF

Capacitors in DB4332B and DB4333B
I am trying to determine the values of variable capacitors in DB Products Low Pass Filters to see if I can convert an 800 Mhz LPF that I bought in a flea market to a 450 Mhz LPF by just changing the

Re: F/S TPL PA6-1AE UHF amp
Sounds like a plan. I have a few other repeaters around that are GMRS or back ups. But if you want to continue this thread, you can email me on my QRZ email, WI9HF. Don't want to tie up the list. Chad

Re: F/S TPL PA6-1AE UHF amp
I fully agree, you would basically just be changing out labels with the name on it. I am just keeping an eye out for a good deal for a spare for our system. I do not want to buy another brand new

Re: F/S TPL PA6-1AE UHF amp
Yeah, I figured the TPLM would work good for my purposes here so I'm gonna hang onto that, but there really isn't any need to sell one to buy another one that's almost kind of silly. Chad Nelson

Not sure what you budget is, I think you said UHF, have you looked at Bridgecom website? They have new Henry Radio Manufacture Amps. I'll link the UHF for easy

Re: F/S TPL PA6-1AE UHF amp
Hi, I will hang onto that TPL amp at this point. I was trying to find another amp, but I am trading apples for apples at this point. Will take advice and keep the TPL. Thanks for your interest.

Re: F/S TPL PA6-1AE UHF amp
You guys convinced me to keep the TPL, so it is going to be put in service with the TK851. Some things I have never tried before make me nervous to try, sounds like I have gotten

All Chad needs do is drop the TKR down to 1 watt and start there... Ken ------------------------------------------------------------------------------ President and CTO - Arcom Controllers Makers

Re: UHF Repeater Input Frequency Issues
The only problem not terminating a divider is causing some amplitude ripple in the passband. It wont hurt the associated amplifier. If the preamp was working it could improve the system noise figure

Re: F/S TPL PA6-1AE UHF amp
The PA6-1AE should be adjustable to and stable at 70w. I second that the TKR-851 will adequately provide a stable low drive output appropriate for your amplifier. You have everything you

Re: UHF Repeater Input Frequency Issues
We've figured out that the desensing was caused by the duplexer being out of alignment. This pictured preamp died in a storm last night causing further issues.? That being said, you're absolutely

Re: F/S TPL PA6-1AE UHF amp
That's only 1.55dB less than 100w, toss another isolator or filter in line with a lossy jumper and keep the amp.
