Thanks for the suggestions. I am using the FA antenna and the “new” FA pro stick plus. I am a pretty chunky guy and I have a really, really steep roof. Those don’t mix! I paid about $200 for a jackleg to mount my FA antenna up on my chimney. It is about 6-8 feet above chimney, on some PVC pipe. I am in great shape in regard to structures, but have several trees that still interfere. The biggest block is to the NW and this shows up clearly on my heat maps. I will not be able to get above all the trees, regardless.
I live in a Historical (Hysterical) District, but am known as somewhat of a lunatic, so the Compliance Nazis have not yet visited. I am sure having an antenna, any antenna, sticking up from this old historic house violates lots of rules, but so far so good.
I had scoped out extending my antenna another 12 feet, using Shed 40 PVC in a Schd 80 PVC pipe for stability. Oh yeah, I am in Eastern NC, in Hurricane City.
I have done a lot of gain analysis and optimization … 43.9 remains my friend!
Still, having stated all that, frustration continues so I am going to move out on antenna extension, maybe give the DPD antenna (http://www.dpdproductions.com/page_vhf_air.html#adsbout a try, AND move the RPi upstairs thus shortening the cable run a little. I just have to find someone to install for me. The last guy about fell and is NOT interested. Imagine, I got a guy who will go to the top of a huge pecan tree using ropes and special boots, but he wont touch the roof.
I have searched for comparisons between the FA antenna and the DPD one. Can’t find anything definitive. As ex government employee, my inclination is to “throw money at the problem,” but would really appreciate some words on the DPD antenna.
The connection to my current antenna is not sealed as good as it could be. I have learned a lot since having it mounted. I DID NOT USE dielectric grease and the tape I used is not as good as the example shown. The exterior terminus, at my grounding block is up to the quality of the sealing material shown. It is quite possible that simply “fixing” the seal between the antenna and the cable could fix all my problems, but I have such limited access to get back up to the antenna.
As always, thanks for your time and thoughts!
