I'm just extremely curious as to why these antennas work so well. They manage to pull in signals that even my Diamond RH789 cant, and even compete with my Wilson 800mhz Yagi. I am not trying to "push" this antenna/brand, I am just perplexed by how it out-does almost all my other antennas, and why it behaves the way it does.
1. It is extremely directional. I have it on a tripod right in my living room, next to my desk, and I revolve the tripod around to pick up different systems.
- for example, one system, which I can barely get one bar of signal on my BCD436HP with the Diamond, and nothing at all with the stock rubber duck, reliably decodes it (especially in DSDPlus, which has near 100% decode rate).
2. It is extremely odd in its orientation preferences. Everything I can find online says that vertical or horizontal polarization are the two main orientations, but this antenna does noticeable better when put in the 1pm -> 7pm position. Picture below:
3. Other than wanting to learn about the reasons behind all of this, I'd also like to know if there is actual reasoning behind this. I've been looking all over for antennas that will pull in VHF/UHF better, but if this isnt just luck I am having with this antenna, Im considering buying 5 of them to keep at a static length for specific frequencies, instead of having to break out the tap measure every time I want to change frequencies/bands (at $12, thats pretty good).
This is the link to the kit and about it:
(my RH789 does well, dont get me wrong, I am extremely happy with it, but I'd like to increase my range for home/base listening)

Using our new Dipole Antenna Kit
Over on our store we now sell our dongles with a receive only dipole antenna kit that replaces the older magnetic whip style antennas from the previous kit. This was done for a few reasons We believe that the dipole kit is much more versatile and will enable beginners to get better reception...
