## Questions & Answers

**Q: Are the Antennas sold in singles or pairs**
A: They are sold single.

**Q: I need something to fix my slx in h5 band, i have dropouts after the fcc packed 5 tv stations in my h5 band! will this help?**
A: same issues with our SLX H5 mics.  I got the 100' premium cable, put the 874 on a mic stand, and plotted it all around the room with an RF Explorer, viewing the RF on my laptop.  I was able to face the antenna away from the TV towers, and also back it up against a metal-framed pillar, and those two changes reduced the RF noise across the H5 spectrum.  Will soon know if it helped...

**Q: Do  i need two for blx24r?**
A: Yes, for true diversity to work, you need two antennas to get best performance.
