    I have a DB Products VHF duplexer in excellent condition for sale. (See pictures) - This duplexer was designed for TX 148.150 and RX 143.900, Right in the middle of the VHF band. It was tuned from the factory at those frequencies and has been untouched. I have included plots for your review. Excellent for a ham repeater and in a nice small package.

    Asking $475 plus $35 shipping to 48 States. Paypal preferred. Contact Jeff AK6OK at ak6ok@arrl.net or PM me here.

    These are great duplexers, but they have a relatively wide TX/RX spacing, so they are not usable on a 600KHz split. They work fine for the wider MARS splits.

    The frequencies listed are NOT in the ham bands either. You might want to post the minimum spacing these are capable of.

    I am unable to find an online manual for this model and so I do not have the actual specs. Please make sure it will work for your application. Thank you! Jeff AK6OK

    I did confirm that this duplexer will not do a 600 khz split. Thanks to all of you who caught this one. Might work as 4 good VHF cans as well! Time for a price drop! Thanks all, Jeff
