Diamond SRH77CA antenna fit on the SDS100

kbrkr · Jan 29, 2020

Is there a specific version of the Diamond SRH77CA Antenna for the SDS100? I'm purchasing another scanner and Diamond SRH77CA and on the last SRH77CA, I had to trim off the barrel of the antenna to fit the SDS100 socket.

Did I order the wrong version or is there an adapter I'm not using?

Yes there is one that is just for the sds100 comes with rubber gasket

Any idea on the sub-model number? Looking on the auction sites, I don't see any difference in models.

I (think) you are referring to the Remtronix 800M one??
It has a gasket - works great - for 800.

The OP is asking about a Diamond SRH77CA, which is a 144/440 antenna.
Of course, if DIAMOND is selling the same antenna, modified to fit a 100, great.
Post links, I want one.

To the OP:
I prefer a direct antenna fitment (no adapter,) if possible.
I (also) Dremmeled a Diamond SRH77CA to fit a SDS100.
If you do it correctly, it works great.
Used some metal black and made it look good.

Thanks

Thanks for clarifying nessnet, I also used my little bench grinder to bevel the base, but you one-upped me by using the metal black.

Perhaps I should be looking at the Remtronix instead. I'm primarily interested in the 700-800 range. I'm using the SRH77CA now and it sounds fine on my 700-800 frequencies.

I have used the BNC version of the Diamond (RH77CA) with the SMA / BNC adapter specifically designed for the SDS 100 and sold by RR member jonwienke

Remtronix 800 seems to perform better IMO

The Remtronix is better on 800, but the Diamond is better on both UHF and VHF.

I use the BNC versions of both on the SDS100 with the adapter mentioned earlier.
