Correct - Because Commercial Sites Don't Have A House - They Have A Structure Or A Cabinet For Equipment. The Structure Or Cabinet Requires Proper Bonding - For Single Point Grounding - To Avoid A Ground Potential Difference.

It's Called Single Point Grounding. Reason - To Eliminate A Potential Difference Between Having (2) Separate Grounding Systems. Single Point Grounding Is Done On All Commercial Tower Sites.

I think you should revisit your original 1st sentence, "building a briefcase repeater using a couple of HT's" - And further address your future repeater site location, including elevations, antenna gain & total loss, as compared to your current HT user elevations & issues. If this suit case repeater will not be placed at an elevated location, in relation to your current HT user areas, such as a tower, hill or mountain top, with the loss in cabling & a duplexer - you will be simply wasting funds. Duplexer tuning, is irrelevant, unless all other parameters have been adressed.

FCC data base shows it was issued on 6.11.2025. Take another look at the date he posted - It's not 6.1.

Sorry, But I Don't Agree With Your Interpretation Of Part 95.1751 (c). #2 - GMRS Stations (Not Operating Under The Individual License) (Other GMRS Stations) Are Properly Identified For The Retransmitted (Repeater) Communications. The Words "If" & "And" Are Key To Understanding The Rule, That's Why It's Very Self Explanitory.

FCC Part 95.1751 (c): (c) Any GMRS repeater station is not required to transmit station identification if: (1) It retransmits only communications from GMRS stations operating under authority of the individual license under which it operates; and, (2) The GMRS stations whose communications are retransmitted are properly identified in accordance with this section. In Other Words, Your Repeater Station Users Are Required To ID, Along With Your Licensed Group Users As Well. Really No Need For Your Repeater Station To Auto CWID - Unless You Just Think It's Cool..... Unfortunately, This Can Cause Issues If You As The Licensee, Do Not ID On Your Station, Due To Auto CWID - Others May Follow Suit Thinking The Repeater ID Is Satisfying Their Repeater Station ID User Requirements. I Do Not Use Station CWID On My Repeaters For Just That Reason.

The Celewave 0185417U05 Is A Good Quality Duplexer, & The Price Is Reasonable. They Can Go For As High As $1150 To $1250, But I Would Pay $500 To $600 For A Good 4 Cavity Used Duplexer With Similar Specs. The 250 Watt Rating Is Less Relevant For GMRS Use, But More Important Is The Isolation & Insertion Loss Specs Of The Duplexer. If You Want A Commercial Grade, Good Quality Duplexer, This Is A Great Choice. It Will Need To Be Tuned By Someone With A Service Monitor, As It Or Any Duplexer Is Specifically Tuned For A Single Pair Of Repeater Frequencies. A Duplexer Is One Of The Main Components Of Your Station - Don't Skimp Just For $$ If You Can Afford It.

Wow - Disappointing..... Thought We Would All Be A Little More Professional With Posts - Regardless Of Personal Input Thoughts & Opinions. Back To The Original Post With A Comment - I Personally Would Not Have An Interest In The Cobra Bubble Pack Unit, Due To The IP Rating & 2.5 Watt Output. The End.....

Depends on the coverage area of both repeaters. If they overlap, you will have interference when both are transmitting at the same time. Having different squelch tones is not the same thing as having different frequencies. My suggestion - Set the second repeater at a different frequency to avoid potential problems.

Wrong Again - No Lesson - A Mis Read On Your Part - Again..... NFPA 70 Is The Standard For The Nation Electrical Code.

NFPA 70 Is The National Electrical Code Sir.....

No, Not Really - You Did Not. When You Take The Time To Read NFPA 70 - Attempt To Understand It - Get Back To Me.

I Do - Do You... Need To Read The Sec I Sited.....

Suggest You Re-Read NFPA 70 - Chapter 810.15 Addressing Communication Site Grounding. (2023 Version) I Am A Licensed Inspector In The State Of Michigan, & NFPA Is Recognized In All 50 States. (Year Of Adoption - Same As Previous Versions.)

That Sir, Is Not Correct. I Suggest You Do Further Research, And Consult The Motorola R56 Manual For Site Grounding Requirements For Commercial Sites. See Link: https://wiki.w9cr.net/images/1/14/Motorola-Standards-and-Guidelines-for-Communication-Sites-R56-Manual_68P81089E50-B.pdf
