A: Yeah, the x50a is a so-239 ....the x50n is a n type connector ...use no less that rg8 feed line ....I recommend lmr400 which is what I use ....73's

**Q: Will this work in the 450-470mhz range?**
A: Yes it will, it works in the 70cm bands (420-450) MHz as well as the 2 meter (144-148) MHz bands. It's a great antenna with good gain and is really well made. Hope this helps.
