good video. just a tip always add some anti-seize to every place you put two parts together (screw in) that way you will never have a issue taking it apart down the road. If you live on the coast its a must. when your dealing with stainless steal its a must to keep it from binding up.
I have the JDT2 which has the 6m vertical on top, and 2 of the lower vertical radiators have loading coils and an adjustable stinger. No instructions on how to tune, I'm assuming these are for the 6m. What say you??
Hi iv got vhf scanner here in Ireland's. iv had a standard sky king fibreglass antenna. but the cable has got damaged over the years. so need a new one would u recommend the discone over the skyking for a uniden base scanner. I usually use it for boats up to 15 mile from my house. l
You are REALLY going to want to put split washers between the nuts and the hub. Wind will cause the radials to vibrate, which will loosen the nuts, which will cause the raidials to unscrew, fall and get lost. How do I know this? It happened to me. I was down to three radials after 6 months in the air. All it took to fix the problem was a set of stainless steel lock washers from the nearest ACE hardware store and borrowing the tall ladder from the friend AGAIN. Why couldn't they include lock washers with the antenna? PROFIT.
It's one level above a Dummy Load because it has No Gain on any band.The receive signals are much better than the transmitted signals with a Unity Gain Antenna.
Overlin Alaniz I'm using the Diamond version of this antenna antenna to Receive/Transmit 6 Meters, 2 Meters, 220 MHz & 440 MHz via some mobile duplexers/triplexers. The SWR on all 4 frequencies is about 1.20:1. The Jetstream should be about the same provided that it has the 6 Meter whip on top. ua-cam.com/video/B-IwfcQrfRY/v-deo.html
Structural aluminum tubing is probably the best, but may be difficult to find depending on your area. A discone antenna like the one Tim shows in this video doesn't have a high wind load, so you don't need anything massively strong like you would with a big HF yagi. I've used 1.5" EMT or IMC conduit from Home Depot in situations like this with very good success. They've survived multiple wind storms of 70+ MPH gusts here in AK with no issues.
😅 It's a copy of radio shack scanner discone antenna . I remeber it was sippose work on ham bands gi swr on 6 meters and 2m 70 cm limited to 10 watts max .
I bought one recently. Came her for install tips. Mission success. Thanks.

I'm about to install a discone antenna very simmilar to yours and your video came pretty handy. thanks!
Just wondering how well it works. I’m looking for a 220 antenna for my attic
Thanks for the video, especially the talk through how it works.
I couldn't tell in the video but I am guessing that there si some type of guying on that 10 ft mast clamped to the vent. I hope so anyway.
What happened to the tripod you showed us?
It's still in use as a portable antenna mount. Penninger Radio makes those; they have several models: www.penningerradio.com/product-category/tripods/

Can you please post a SWR plot for that antenna from a VNA like e.g. a Rigexpert?
Where did you get that cool tri-pod?

+seamus doohan I would need to see a picture of that sky king to understand what it is before I could answer that question

Does this work for 137mhz noaa weather data collection?
+Ryan Jefferson Yes
Yes is does... NOAA operates at 162.550 MHz in our area...
@@wolfgangsnitsar4739 The Wx Satellites are on 137Mhz
What is that other antenna beside your discone antenna?
It's a Gizmotchy 2m dual polarization beam

What coax are you using?
He said,Good Quality RG8.He should be using 9913,LMR 400 or LMR 600 at least since the Loss is very high on those bands with RG8.
Nvm my jetstream has a vertical single stick on the top in addition to this
Would this work with a 50 watt vhf/uhf base radio? And what kind of reach do you get running vhf?
+Sean Maples Yes it will handle 50 watts. You should understand that it is unity gain.
It's one level above a Dummy Load because it has No Gain on any band.The receive signals are much better than the transmitted signals with a Unity Gain Antenna.
Wow i had no idea u could transmit on this. I have one that i bought for my bct15x scanner.
Those antennas look really close to each other.
I've got the same antenna in a Tram version. What kind of SWR readings are you getting on 2m, 70cm, and GMRS?

@@AlaskaMike72 ... The top horizontal rail of a chain link fence works great for a mast... cheap too... :)
@@wolfgangsnitsar4739 Yes--that's also an excellent choice for an antenna like this!
Great video...thanks!
Perfect for the Icom 9700,
1250MHz is 1.2 GHz.

nice
👍👍👍👍👍👍👍
Lol u said 1.3 mhz!!!! xD instead of ghz
I too am totally confused by this 25 to 1.3 mhz sounds like a HF antenna not a vhg uhf! Anyway its rather cool looking!
👍👍👍👍👍👍👍👍👍👍👍👏
