Two antennas on 2-meter isn't exactly doable, the vertical and horizontal spacing issues would make it prohibitively undoable for a mobile repeater platform.
You might find a mobile duplexer with 1.2mhz spacing (I remember someone here on RB talking about such a unit some time ago), but like Chuck said... 600khz is going to be a hard if not near impossible find. That is if you don't mind four normal duplexer cans taking up the entire back seat of your vehicle. -Brian / KF4ZWZ On Wed, Oct 7, 2009 at 4:55 PM, Chuck Kelsey <[email protected]> wrote: > > > You won't find a mobile duplexer for 600 kHz spacing. > > Chuck > WB2EDV > > ----- Original Message ----- > *From:* [email protected] > *To:* [email protected] > *Sent:* Wednesday, October 07, 2009 7:36 PM > *Subject:* Re: [Repeater-Builder] Question on portable repeaters > > > Vertical and horizontal distance with be significantly different, with > vertical being smaller.
