Testing homebuilt antennas for the last three weeks versus an FA antenna, and had some surprising results. To verify data, Looking for volunteers who are willing to test antennas.
Recently I had some problems with FA antenna. During the winter storm last month it got water.
Red arrows point to places where water was accumulated.
In the mean time I made homebrew colinear.
After drying it up I was curious to compare FA antena to homebrew colinear.
Both antennas were hanging side by side on the window inside for some time
and showed similar performance with slight advantage in distance for homebuilt.
You can see that dongles are different, that might be also a factor for slight better performance for colinear.
Then I put FA antenna outside and replaced Nooelec dongle with RTL-SDR.
Both setups are now with RTL-SDR v.1 dongle but different batches.
Software is modesdeco both instances of it running on a desktop Dell.
Here are the results after several days of work
FA antena outside.
Homebuilt colinear behind the window.
The coverage with homebuilt antenna is narrower because of the place.
Both antennas are at equal height from the ground - about 30 meters.
They are 3 meters apart and the only difference is that one is behind the window
P.S. As for the FA antenna I must say that once it was dry it performs as before.
