He dude I had one made about 4 years ago. I love it. An alligator wombat storm came through about a year ago and blew it over. Didn't put a scratch on antenna. I had 5 guy wires and it still blew it over. Just took it loose from chimney and put it in basement. Gonna put my imax 2000 back up, im retired an can't get around so that's about all I can do. All my friends are gone that could help me so I have to do what I can. I have 4 or 5 big power units the imax will handle because I don't talk much anymore. Couple have 750 to a 1000 watts an one has about 3500 watts. Imax worked ok then so it will now I guess. You got a good one.
Interesting, MY Ø5 Colossal came with a capacitance hat for the top which helps to lower the Q and widen the useable bandwidth, not a simple rubber cap. There's no need for parallel capacitance to ground unless there's series capacitance, such as a capacitance hat, on the tip of the radiator because the impedance matching ring finds 50Ω between the 200Ω radiator and 0Ω ground @ Ø reactance. - No other successful 5/8 utilizes parallel capacitance to ground except the MACO V58/5000 and that is fictitious in terms of any helpful capacitance occurring between the bottom of the radiator and the ground bracket since it's is negligible at best and proven to be so by raising the radiator up and out of the base onto a fiberglass rod insulator and finding as we did - that there's no difference in tuning nor performance. CB myths abound and are almost measurable by the DB! 😁😂🤣
It makes no sense to use such long radials, in every simulation you can see that several shorter radials bring a higher gain to the antenna system and the antenna is better balanced, especially in the far field. It is better to use about twenty thin top loaded mobile antennas with 3/8 threads which are shorter than a quarter wave and that have been tuned to resonance frequency with an antenna analyzer. Calculations show that 1/4 wave radials are more difficult to symmetrize in practice, phase cancellations is the result, the antenna no longer radiates evenly. If you have the space, it is best to place your antenna on an approximately 50 foot tower, or higher At this height, a 5/8 antenna on the CB band radiates very flat and most efficient. The rule applies to all antenna structures: It is better to invest first in the height of the antenna, then in the antenna.
Just shows the glitches & failures of antenna design programs. In field testing, a Three 1/4 wave radial counterpoise exhibits the highest efficiency at the lowest TOA along with the most (incidental) horizontal energy. A 1976 Hy-gain Penetrator will wipe the floor with a Sirio 827 and tie or best a Vector-4K - depending on distance. Tested and proven, each to each and each to the other at 10, 25 & 50mi.
I've even gone so far as to remove 3 of 4 - 1/4 wave radials from the Hy-gain Super Penetrator and mount it on a rotor so I could spin it 360° and there was ZERO difference to 4 different various distance "local" stations. The only point where I saw a little gain was incidental horizontal performance to a Moonraker-4 with three 120° 1/4 wave radials (instead of four 90° 1/4 wave radials) - on the same Super Penetrator.
In two steps: 1) Adjust the inductance arm for best SWR at desired frequency 2) Adjust the capacitance piece for final SWR adjustment Its basically a parallel tank circuit

That antenna looks like its built solid like a bick!!!👍👍👍
Really wish this antenna was available in the UK. It looks very well made!
It's been 4yrs since you posted your comment, were you ever able to get one?
@@RU2AIM unfortunately I wasn’t able to get one.
Have been using a 4BTV & separate long wire for the 80metre band.
@@iain777uk So am I to infer you've left behind your distant 11m relatives? 😉
Mine is identical. It will work well for you. Mine came marked where they should come together.
Can you provide the specifications of the matching system you installed? Also what kind of SWR are you getting?
So, how good a Talker
Especially on DX is it
Looks Very well made
I had an I-10k that did very well for yrs
Dont forget to use "COPPER" Anti seize on all the slip joints and ground radials. DONT use Dialectric grease for its NON CONDUCTIVE!!!.
Nice
Nice antenna I would like to have one of those
hello 1911 chicago how much feet haved a 4 radial on the barrow and how much feet mast on the top thanks
How is this antenna working out? I'm thinking about getting one
I have a 10k it kicks ass you will like it the antenna is built like a brick wall one 10k went threw hurricane sandy in NJ 150 mph winds
Hi, Would it help to put bulb grease on all the connecting points when putting it together?
what bands does this cover ?
I have the zero five 10 k colossal, still in the box, brand new, untouched
lol friend it's not doing you any good in the box , you need it up and ready to get on air , we need get more CB operators on the air
Yes, you should definitely touch it..
They apparently don't offer the 5K model anymore, $350 for a ground plane antenna is where two fools met...

My Hy-Gain Penetrator is over 40 years old and still doing a great job. (Though retuned to 10m since I became a Ham.)
I've even gone so far as to remove 3 of 4 - 1/4 wave radials from the Hy-gain Super Penetrator and mount it on a rotor so I could spin it 360° and there was ZERO difference to 4 different various distance "local" stations.

whats your swr reading is it easy installation for one person
Now that you have had the chance to see what this antenna is about, what kind of report can you give on it?
Bo Mo this antenna is great. Has great receive. And the price was $299.99 at the time when purchased.
How well is the antenna working for ya?
Any videos since you now have it in the air?
Thoughts on current price now?
The prices have increased since my purchase.
No video on the roof posted yet.
Boa tarde amigo! Como eu consigo uma antena dessa ? UM forte 73!
Wow. Looks expensive!
Was the antenna kick ass or what??
Yup 5 out of 5 stars rating. Should of bought one when I first posted this video. They went up in price!
how do you tune this antenna?
In two steps:
1) Adjust the inductance arm for best SWR at desired frequency
2) Adjust the capacitance piece for final SWR adjustment
Its basically a parallel tank circuit
Nice. Snow Man 111MILWAUKE Milwaukee Wisconsin
What mounts ?
GLEN MARTIN ROOF TOP TOWER
Is it better than the mr coily? L
I am not sure never owned or seen one in person
Those hose clamps are junk, id put some non binding "T-Bolt" clamps instead!
Nice-----
Where can we get this antenna?
You can call Tom directly or order from the website. www.zerofive-antennas.com/product-category/colossal-58-cb-antennas
Junk😢
