I have four steel funnels that are manufactured by Behrens. I had been planning on some antenna testing, but I just don’t have the time. I’m happy to ship these to anyone who has the time to conduct and document a couple hour’s worth of backyard experiments. I don’t expect spectacular results from these funnels, as the angle of the funnels is twice what the actual horn is on the LNB, but there should be some improvement (60-degrees vs 30-degrees)
In addition to testing with both a naked LNB and one with the plastic case on, it would be interesting to see the SNR of all four sizes; so a total of 8 different data points. The best way to share this information is through a blog post, which we are happy to cross-post from our site. Here is what I can send (all free):
- four different funnels of varying sizes
- two LNBs; one to be tested with the case taken off
- Dreamcatcher for testing
I mapped this out as a Saturday afternoon project, so the goal would be to have the post ready to publish about a week after the package is received. The only requirement is that you need to be within the coverage area and have participated on the forum at some time in the past. If there are several interested parties, then we’ll let the forum members on this thread determine who should get the kit.
