Re: [Repeater-Builder] UHF Duplexer Question

Joe Not sure which kind of duplexer Motorola uses in the MTR-2000 but in the MSF5000 they use a Tee Duplexer and a TFE6492A tx filter. In my oponion it works like crap. The duplexer that I like best is the the Cellwave(RFS) or Phelps Dodge style 526. I am using these with 2 UHF C74clb MSF-5000 a

Motorola uses the six cavity celwave rack mount (very expensive).  I would suggest the tx/rx units over the celwave. I use the tx/rx 4 cavity units on all my repeaters, even the one running at 200 watts. [EMAIL PROTECTED] wrote: I currently have a UHF MTR-2000 repeater, I bought it

[Repeater-Builder] Re: filter question (test time)

Turn the Repeater Power Down to 20 watts output. Borrow a 3dB attenuator that will handle 15 watts and intert it in the line between the rf pa and the duplexer. Test the system again using weak signals (run around your normal locations with ht's). Less the reduced repeater transmit power out

TX RX in Angola, NY has BP/BR duplexers that seem to be the most popular for high interference sites, in my opinion. Depending on the level of interference you may need additional filtering which they also make. Good Luck JIM   KA2AJH     - Original Message - From: [EMAIL

Re: [Repeater-Builder] 2 repeaters / one antenna

I would recommend lightning protection (specifically Polyphasor). Since it should be at the enterance to the building, and the duplexers (the two on the repeaters and the one combining the repeaters) should all be inside the building, they would all be protected. That should eliminate the lightnin

Re: [Repeater-Builder] Does the R100 need duplexer if using two anetnnas?

Point taken. 1/4 wave antennas are not truly isotropic. The vertical seperation can be much less if gain antennas are used however, and gain antennas give better coverage further out, which is usually a benefiet. Wade - KR7K - Original Message - From: "Tony King - W4ZT" <[EMAIL PROTE
