    Hi John,
    You have a good plan there to build a collinear.... I have great appreciation for that simple antennas abilities! Amplifier will also work wonders... do look at the advise and information posted from ABCD... he has done a lot of testing and experimenting to figure out the best antenna to use. Amplifier as close to the antenna as possible, might also render better results than having it indoors.
    Also, to get some more height would be a good idea.

    Although I have occasionally observed aircraft out to 200 miles in all major directions, this plot confirms that, on average, my effective range is only about 60-80 miles in most directions, except for the Northwest quadrant, which has the least obstructed view from my simple home-brewed ground plane antenna.

    The antenna is currently mounted below the roof line on the Northeast corner of the house, so I was surprised that reception to the South doesn't seem much attenuated. But the view to the North and Northeast is mostly blocked by a forest of 60 ft pine trees, less than 100 ft away. It would seem that a grove of pine trees has roughly the same RF absorption as a 2-story stucco framed house. :-|

    So this is my 'baseline' for making and comparing improvements. I plan to 1) build a collinear antenna 2) mount it a few feet above the eaves of the house and 3) insert a 20db satellite line amplifier at the base of the antenna.

    The cable run to the receiver will still be less than 25 feet, so I'm expecting these improvements to enhance my coverage considerably. :-]

    Tnx,
    John/af4ex
    The hobby to get more is addicting isn't it? Keep in mind the satellite amp is designed to pass on the DC power beyond the amplifier, so take that into consideration with your antenna design.

    Glad to see you got everything working!

    Thanks for all the good info and tips. I'll report the results of my improvements after I've built and tested them.
    Tnx,

    Post Glenda/Rammasun Typhoon Philippine Update

    Typhoon Glenda/Rammasun has now passed the Philippines leaving destruction and power outage for millions across Luzon (Manila) and Albay (Legaspi). These two areas are where our feeders are located.

    The results of the typhoon destruction and loss of power on our FR24 network are this:

    Working either on generator or a typhoon proof location:

    F-RPLL1 (Manila) Manila NAIA Airport, Ok, not interrupted feeding.
    F-RPVM1 (Cebu Mactan Airport) No Serious exposure, Online Reliable.
    F-RPVT1 (Bohol) Bohol Tagbilaran Airport, Online, No Serious exposure.
    F-RPVD1 (Dumaguete/Sibulan) Negros Oriental, Dumaguete Airport, Online No serious exposure.
    T-RPVD2 (Siquijor Province) across from Negros Oriental, Dumaguete Airport, Online No serious exposure.
    F-RPWD1 (Davao) Davao Mindanao Airport, Online No serious exposure.
    F-RPMZ1 (Zamboanga) Zamboanga Mindanao Airport, Online No serious exposure.
    F-RPVB1 (Bacolod/Silay) Negros Occidental. Online No serious exposure.

    Locations that are offline due to typhoon destruction-power outage or other problems:

    F-RPLL2 (Manila) Off-line
    F-RPMB1 (General Santos) General Santos receiver site has been missing for a long time due to unknown reasons.
    F-RPLP1 (Legazpi) Legazpi Albay Airport. The typhoon eye wall followed the coastline and had 185 kph winds probably destroying the receiver site. Power outage alone will keep it off line for maybe a week even if the location was not destroyed.

    Two new receiver locations in the Philippines should show up this week.

    Due to privacy concerns there has only been limited contact here in the Philippines to collaborate among ourselves.

    Again those here in the Philippines who wish to network here are my local numbers:

    Globe 09166038327
    Smart 09085291286

    Thanks for your detailed assessment of the receivers in Philippines. Yes I note there is two new receivers out of the 3 that is still waiting to be activated. Hopefully one will be around Pahlawan/Puerto Princesa... fingers crossed.

    I think the FR24 system is under severe strain at the moment, due to the Ukranian/Malaysian incident. My primary feeding system can't even connect to the FR servers at present. But let's see what more informed responses you will get.

    I know FR24 only take ground traffic from a few feeders - my guess that is because most don't see it and any they did report would probably be crap data.

    If you're are in a great position to see ground traffic and traffic low to Paine field - why not apply for a vaunted FR Box? It might be worth it if you could make a significant contribution through that box.

    Just curious if your feeds did show would the be via the PP notwork or as a T- radarcode

    Tracert from the Philippines shows major transit network problems to the FR24 web page and the feeder server. It is 14:37 UTC as I send this.

    Packet loss at the FR24 servers running about 70%. My ISP routing through TelstraGlobal has greatly reduced my latency to an average of 327 ms.

    Mlat3 is a casualty of this present network problem. Other Mlat areas are displaying fine just the one Mlat3 for Australia-New Zealand is dark.
