so to finalize this test i also built the well know 8 legged spider to compare against the J-Pole and Slim Jim. All element lengths are 69mm as per tutorial on this forum.
They all show very very similar reception range, but in my opinion the J-pole wins as its far simpler to build and just as...
Now i've found this 1..... :rolleyes:
it would appear there is another version available
Although the advert gives incorrect frequency range as this one is 1.1 Mhz to 1.3 Ghz so will cover all HF,UHF and VHF bands...
Hi, just a quick question..... is the VNA AN121SA worth the money???
I can get 1 from ebay around £140 delivered
Are they any good?
my current VNA AW07A unfortunately doesn't go high enough.
Thanks for reading ;)
after 12 hours using cheap'o ebay DVB stick un-amped un filtered
I'll leave it running till 8pm tonight (another 12 Hours) then switch over and leave the Slim-Jim running for same time.
I'm impressed with its performance so far, might run a test in a few days with it up a mast.
