Its Massive
I have the 24th Edition which has been updated over the years so curious to see if there is some new content or updates
I suggest you buy the print edition for those that need to hold paper

After ordering, it takes awhile to get the download link. Their servers are
I am a member so not sure if its available to non-members
Note: They will send a download link but it may take a bit of time as they process the orders
I expect a lot of hams will be downloading this because its FREE. Hams love FREE.
If you “bought” your license (this is normal in the Toronto Area) and do not understand SWR then you may wish to download a movie instead. I heard a new ham on the repeater asking how to make a dipole and asking about SWR. An older Ham explained it to him but he was also confused and gave out the wrong information. After a while it became clear that the old ham doesn’t operate on HF and may have forgotten what it was like in the 1950s when no one really bothered with SWR due to tube based transmitters having LC circuits built in. The stumper became “How do I measure it?” and the 5 pm dinner bell rang and the repeater went back to “crickets” mode after its ID.
This is for CB but will work in a pinch and is what I used when I got licensed and used a home made transmitter on 7040 and 7115. Why did I have a 7115 crystal in my radio.? Why did it take many CQs over several days to get an answer with my 40m antenna at the same height as my Moms clothesline?

Anyways I have operated with antennas at 3:1 with no worries (Wow those FT-891s are tough) and for 3 months my mobile was transmitting into a broken antenna with a SWR of 10:1. God Bless Icom…tough radios
Buy a Rigexpert to make sure you have accurate readings.
Yes sir it covers up to 446 Mhz and even GMRS
QUESTION: WHY IS THE 40M SWR SO FREAKING HIGH? A PRIZE WILL BE SENT OUT FOR A CORRECT ANSWER
If he took my radio class he would have made a J-Pole and a 20m dipole in one of the classes. Plus a lot of practical stuff that is needed once licensed.

TIE BREAKER IN CASE 2 ENTRIES HAVE THE SAME TIME STAMP
Based on the bandwidth shown what kind of antenna could this be?
