yes that will do it.
With this type of antenna, would DC blockers be needed if using an amp and power injector?

It’s never a bad idea to use them with a power injector.
I’d use a test meter to see if there a DC continuity between the centre and outer connections of the antenna - if there is no continuity - you don’t need a blocker.
Maybe someone who has both the antenna and a suitable meter can do the check … it would take longer to type a response than to do the check.
The one I have has no continuity (I’m not sure if it’s exactly the same as the one FA is shipping)
I received my FA antenna from Amazon yesterday. I’m going to install it tonight. Updates to follow. Thanks FA the antenna and mounting bracket looks real nice. 
I am not sure if I expected to much, but 24 hours trail (just swapped the antennas on existing setup) indicates that the only difference with my 4 legged spider is very slight increase in number of positions from one sector based on the FA stats page. Is there an easy way to check the antenna?
Possibly my antenna building skills are not great but I am defiantly seeing a noticeable increase of both positions and range.
I have made 8 & 11 segment COCO’s, Spiders 4 - 8 legged variety and none of those has worked better.
The site is started testing at a site that is in a valley. This severally limits my range in most directions to less 75 miles but the max range has been as far as 150 miles (further then before).
For the price point I have found it is a excellent antenna for my needs.
I recieved my FA antenna today. I thought I had a multi-meter somewhere to check the continuity, but could not find it. I installed DC blockers just in case.
I swapped out the window 4-legged spider on my secondary RPi with the FA antenna. I’ll give it a few days and then compare the before and after PF polar plots, since this RPi also feeds Plane Finder.
The construction quality of the FA antenna is very good.

Any word on availability of the filter/amp? Need any test/measurement sites?
I helped infect a good friend with the ADS-B bug, bringing up his system. It’s working, and we even see blue MLAT aircraft!
The counts aren’t that great as he has a monster cell tower less than a km away; filtering is definitely called for!

I just wired this in today:
adsbfilter.blogspot.com/
1090 MHz filter, amp and DC blocker all in one. Waiting to see what the results are.
We’ll announce filter availability here, but we’re still a few weeks away.
Any word on availability in Canada? I’d really like to order a filter/amp when available.

That would be great…looking forward to it.
How are the results??
I have one sitting on my desk. Been too busy for the past two weeks to install it. I also got a small 12VDC power board for it.
How’s it working?
It has no amplifier.
it is just a SAW filter and power injector …
… the amplifier is a companion product LNA4all lna4all.blogspot.com/ … but be aware to use ‘ip the line’ injected power you have to source and fit your own surface mount inductor to the amplifier board. (read the writeup)
I’m running with a surface mount SAW filter cut into the R820T pigtail - no circuit board - seems to work OK.
any update on the update for the filter … ???
Does it matter if the FA antenna is mounted to a metal mount via the U-Bolts or to a plastic pipe ? Does that affect grounding ?
The reason I ask is that I can extend my metal mount using a plastic pipe to get a couple more feet over the rooftop. The attics in Florida houses is lined with metal foil to reflect heat and so block signal greatly.
Should be OK.
