Good Morning,

I have the following UHF duplexers and cavity for sale:

1. Celwave 6 cavity mobile duplexer model TDN-7407A=20
450-470 Mhz. I'm told this one is good for 45 watts. I have no other
information. Very good cosmetic condition and I am told it was pulled
from a working installation. $125

2. Celwave 6 cavity mobile duplexer model TDE-7780A=20
450-470 Mhz. This one is also supposed to be good for 45 watts, but I
have no other info on this one either. Very good cosmetic condition,
and am told it was pulled from a working installation. $125.

3. Telewave 4 cavity pass-reject duplexer model

I'm sorry, but I don't have the facilities to evaluate
these duplexers/cavity or tune them. Digital photos are available on
request and of course you can email with any questions.

Shipping from 95608 is additional on all items. I ship
FedEx Ground in most cases. The mobile duplexers may be able to go
USPS Priority Mail flat rate box if desired.

Payment: PayPal is accepted and preferred. PayPal lets
me ship your item a quickly as possible. I will also accept USPS
money orders and cashier's checks. No other form of payment is
accepted. I reserve the right to hold money orders and cashier's for
a reasonable period of time to ensure they are genuine. (The post
office tells me forgeries are becoming more common.)

Sales only to the US and Canada. Canadian buyers: I will
not lie on customs forms. Don't ask.

Thanks for looking.

Dennis
