Hi everyone,
It's probably a little late for most, but if anyone is planning to purchase any number of PLC1669 - 9 element Yagi antenna, the price is due to increase May 1, so you may want to act quickly. Not sure if that's across the board, or just this supplier.
Cheers,
Stu

I just wanted to update you on the pricing of the PLC1669 antennas. They are due to increase to $309.61 on May 1st. I know when you asked for the quote in February, due to deadlines, you only ordered the cables and not the 10 antennas. Not sure if you wanted to replace your stock of these antennas while they are still at $295.86. It would be a savings of $137 if you order now.
Thank you.

Thanks for your input John and Bryant,
I've had some success with this code after learning about the dplyr package.
library(dplyr)
B337group <- group_by(B337t10,site, day(B337t10$ts))
B337meansigperday <- summarise(B337group, meansig = mean(B337t10$sig, na.rm = TRUE))
It works in the sense that it separates the signal strength per site per day and seems to calculate the mean, but it returns all the exact same value for the mean?
Thanks,
Christopher
