If you own the X7 and possibly the X9, you will find that the antenna
matches nicely on 40m without the 40m add on option. On the basic X7
without a tuner I have an SWR of 1.7/1 at the low end of 40m. On the
american frequency allocation you should be able to get an even lower
SWR higher up the band. I have compared the received reports with a full
wave 80m horizontal delta loop and the X7 was within 3 dB. There is no
detectable difference on the front to back, but if you just want to get
a signal out on 40m then the basic X7 will allow you to do this.
