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

Dude - You Are Spot On....... Some Folks Are Just Plain Ignorant With Their Self Justified Rational / Reasoning......

You Need To Ground The Tower Leg. The Antenna Is Already Connected To The Tower For Grounding Purposes. The Coaxial Cable Should Also Have The Shielding Bonded To The Single Point Ground System. Unless You Have A Particular Type Of Commercial Antenna That Has Designated Grounding Straps At The Antenna - The Type Of Stick Does Not Matter. A Lightning Arrester Is Also Recommended - PolyPhaser Makes An Excellent Arrester, Used Frequently On Commercial Radio Sites.

So Put Up Your Own Repeater On That GMRS Frequency. He Owns The Repeater, Not The Frequency Or Squelch Access Tones. Repeater CWID Is Not A Requirement, Nor Is That Relative. Not Sure Why This Is Such A Big Deal. The Repeater Owners Have Their Option For Allowing Use.

Rules Seem Pretty Clear To Me. 95.1705 Individual licenses required; eligibility; who may operate; cooperative use. (d) Individual licensee duties. The holder of an individual license: (1) Shall determine specifically which individuals, including family members, are allowed to operate (i.e., exercise operational control over) its GMRS station(s) (see paragraph (c) of this section); (2) May allow any person to use (i.e., benefit from the operation of) its GMRS repeater, or alternatively, may limit the use of its GMRS repeater to specific persons; (3) May disallow the use of its GMRS repeater by specific persons as may be necessary to carry out its responsibilities under this section.

You Just Posted It..... Another Attitude - Please Re-read My Post - Or Not...... Peace Out.....

OMG..... Unbelievable.... Maybe All You Folks Should Consider Talking On Your Radio Stations Instead Of Constantly Arguing, Bickering, & Discussing On How They Are Supposed To Perform Better According To Your Opinionated Logic Of The GMRS / UHF Frequency Band, & Everything Else Involved....... Not Sure What Else To Say, But It's A Pretty Sad Rendition Of Folks That Should & Definitely Know Better With All The Knowledge That Exists On This Form. Folks Just Need To Loose Their Attitudes & Share Their Supported Knowledge........ Thx Bob Somers - WRXL702

If The Repeater Owner Has Previous Approved Or Denied Requests Attached To Their myGMRS Repeater Log, The "Request Access Disabled" Function Is No Longer An Option, Regardless Whether The Station Is Listed As Open - With Or Without The Squelch Tones. The Only Way To Correct & Have That Option Available, Is To Delete The Listing, Which Deletes Previous Requests, & Re-post The Repeater Station. Some Repeater Operators In WI Done That When They Went From A Paid To An Open Repeater Station.

The Frida 700 Station Has Never Been Built Out Or Put Into Service. Some Folks Like To Post A Station To Mark A Geographic Area They Are Considering For A Repeater Someday. The Problem Is That "Someday" Doesn't Seem To Happen. You're Welcome To Put In A Request For My Niles 725, It's In Service & Has A Good Footprint For South Western Lower Michigan & Northern IN. You Will Also Receive The Indiana Osceola 600 Which Covers A Portion Of Southern Michigan As Well........

Then Folks Should Refrain On Commenting "Not Quite" If They Are Siting An "Example / Opinion" Of Documented FCC Definitions.....

FCC Part 95 Subpart A - 95.303 Definitions: Base station. A station at a fixed location that communicates directly with mobile stations and other base stations. Fixed station. A station at a fixed location that directly communicates with other fixed stations only. The Term "DATA" Is Not Referenced In These Definitions For The Type Of Transmission. https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-A
