My unmodified DB224 had a VSWR of 1.8:1 in the 147 Mhz portion of 2 meters, in the 145 Mhz portion it went over 2.1:1. After the modifications it went down to 1.6:1 at 145 Mhz. On the receive portion I did not notice any changes, in the transmit, it did improve the power output, as expected. It
I did, and I am happy with it. 2 meters is well centered for that
antenna, and the SWR is nice and low.

We notice the popular model covers 150-160 MHz.
Also available is a model covering 138-150 MHz, for about $50
we have a 150 to 160 one on 2 meters and the coverage is not as good as it
could be.

If this is for a repeater you definately want the one
designed for 2 meters. I've been screwing around with
modifying one of the 150's for months trying to get
the swr down. It would have been worth it to buy a
new one for 2m in the first place after all the time
you put in to it. Paul, kb9wlc,

I've heard many times that the 150-160 model covers 2 meters just fine.
In fact we have a DB-264 with 150-160 MHz specs and it
5 matches
