Guys newbie to the forum but been in CB for awhile thinking of retiring my Sirio Tornado 5/8 ground plane and thinking of maybe one of these
collosal 10 k antennas I know price is a tad bit steep but is the antenna worth the money and how hard is it to tune,my Sirio was very easy to
tune and performed very well just looking for something better,we just went through a cat 1 hurricane and the sirio took a beating so I am
looking for something a bit more robust any knowledge of the colossal would be welcomed and thanks in advance.
 

Thanks guys is there anything out there that is robust and that performs as good or better than the antenna mention above,I also was looking at the Hygain penatrator 500 I think it was but heard some people were having some tuning issues with that one and also the Maco v58,I do like talking skip when its rolling in Louisiana I just might stick me a beam up there don,t know yet thanks again guys.

I don't know about the others but I do know the maco v58 is an outstanding antenna. A little tricky to tune until you get the hang of it then you just let it be. Maco recently put out some videos with tips and tricks to tuning. They way they set the antenna up was super easy compared to the way I did so if you go that route the vids will make it a breeze.

I did own it, was a great antenna both local and on the dx side of things. Unfortunately for me a brutal Texas panhandle thunderstorm broke the bottom section right at the insulator. They did send me a replacement bottom section and the antenna sits in my attic to this day.
 
The colossal 10k is built way better than the sirio . And most likelybetter then spt500 and maco..it should perform just as good as the sirio ...not sure about better.
 
My SPT500 has been up for probably 10 years or so, has survived some 80 mph winds. The tuning aspect I think has been found to be a factory issue that was reported here on this forum some where. I think the DX Engineering site has the info on the wrongly assembled part that has been hopefully corrected.
I had 2 iMax antenna's before...1 snapped, the other was replaced before it snapped. The SPT500 sure is a lot quieter than the fiberglass.
The colossal 10k, although never having seen one, seems to have the advantage of a better quality materials and build.

Hy-Gain SPT-500​


Excellent when assembled properly, Not made as heavy as the original from 1970's but such is the american Way!!
PLEASE READ!!!! If you have problems getting a resonant antenna, Mine was assembled wrong at the factory. the center conductor from the SO-239 was internally attached to the wrong terminal. Needs to be attached to the side terminal not the center.. If not this will never make a resonant antenna..

Hy-Gain SPT-500 is no longer in production.
 
I have a brand new , in the box, N.O.S. 80's model SPT 500........
I am willing to sell it, but not at the latest SPT500 selling price.....
The Penetrator hasn't been made like this is a long, long time.....

Thanks guys for the come backs looks like we may have another hurricane in the Gulf by next week I have a thirsty Generac diesel generator that I might have to buy fuel for so I may have to hold off a bit before getting a new antenna set up, but your replies have sure open my eyes up to some of the antenna flavors out there LOL !!!! thanks again

SPT-500 assembled wrong from the factory video.





Maco V58 assembly by Maco Antennas. For some reason I can't link the Maco antenna assembly video.

I bought the Maco V58 a few months back, and it works very good. Just get the hoop right. Had the SPT-500 that would not tune, and it got sent back for a refund.

I do have a ZEROANTENNAS Colossal 10K antenna also. I have had it up for several years.
It is a very robust antenna and I use it on 10m and 11m.....
 
How is the receive and the TX on that antenna I am leaning towards it because of it being so robust,also looking at the Sirio 827 but kinda hard to find locally and something I also remembered from my other Sirio parts were hard to find for that antenna,choices choices!!!!
 
I have available the new updated release Workman W58, with reinforced bottom section. It is a true 5/8 base station antenna. Best bang for the $$$ out there right now.

Receive and transmit are as good as any 5/8 wave vertical. Maybe somewhat better than most......
Being so robust and well made is what attracted me to the Colossal 10K.....
