Video # 1 HF Vertical Project Comet CHA-250HD HF/VHF Vertical Antenna Prep for Install

Follow-up Video with Test Results:
• Video # 2 Comet CHA-25...
This video is an introduction to a new HF Vertical from Comet. The HD series has a smaller whip in the end to reduce wind drag over the CHA-250B and CHA-250HDII - This is the 1st video in a series of the project - next video I will install in place of mt existing CP610 for 6 and 10M. The SWR curve looks exciting from the brochure and I will be installing new LMR 400 50 section of Coax from DX Engineering more details to come 73
This antenna can cover 80, 40, 60, 20, 17, 15, 10 and 6

Just bought one. I use the 25' Cha Porta mast and go portable with it. Everything fits broken down in the back of my pickup. I fit it to the top of the mast on the ground and lift it into the porta mast hitch mount, get in the back of the pickup, and elevate it.

Hi and thanks for the message I just looked that up very cool and looks like very high quality - let me know how the tests results come I might me interested in making a video and trying love the hitch mount idea, thanks again 73 from KI5JUF also I did a video on the radiation patterns:
Comet CHA-250HD Performance Max Take Angle / -3dB Lobe Intersection / + 3dB Band Width 10/35 Feet

I have my Comet250B set up on a temporary tripod .. hope to get my tower up before the snow falls.

[@westtexasvideogateski5juf255]

Hi Michael, thanks for the message, good luck I have some data from COMET showing the take off angles at 10 feet and 35 feet for 80, 40, 20, 17, 15 and 10 with the dB loss I'm putting together some information let me know if you wat to see the data sheets I'll send them to you [e-mail] okay my friend 73 hope to catch you on the air my friend

I have the Twin one Falcon 250, but antenna is complete depth.

[@user-zk2yd6xm8s]

Dummy load on a stick with cooling fins added nice touch.
Actually a traveling wave antenna but a poor example since the radiation element is fairly small unlike its distant cousin the mighty 1200 foot rombic who also use a termination resistor although the good ones had a tune network. Also in the family are receiving beverages coming in at 800 feet and vee beems and of course the terminated folded dipole another dummy load.

Thanks for putting this together. Any concerns with the Anit-sieze lub impacting connectivity between sections? I'd also be interested in yoru experiences using this antenna. Thanks!

[@ATOMSHAMRADIO]

Love the design

[@dsolo3250]

I talk to New Zealand from Florida with one of these on 10 meters. It’s my first antenna. Why is this a dummy load? Please explain why this antenna isn’t good. I’m still learning

[@ATOMSHAMRADIO]

I like it good info on that antenna

[@DK5ONV]

Not a bad Multi Band Antenna for it is if going vertical is the only Way for you to get on the Air from home or a tiny Vacation Place

I don't think the lock washers should go underneath the heads of the bolts. They should probably go under the wingnuts.

[@westtexasvideogateski5juf255]

Good comment good for everyone to see, so far it's been doing a good job, thanks for the message and 73 sir

[@ATOMSHAMRADIO]

Bottom part is a balun

[@westtexasvideogateski5juf255]

Thanks for the messages appriciate the feedback, I ran out of time on cameral, but I thank you for messaging me, my plan is to take down the CP610 mouted 30 ft up, instlall this antenna and rund some SWR sweeops and share my results. Thanks again, I'm excited I really wa impressed with Coment as with most Japanese companies there is a lot pride i the work - ok thank you so much more videos to follow 73 de Ki5JUF

[@ATOMSHAMRADIO]

@@westtexasvideogateski5juf255 cool keep us updated

[@user-zk2yd6xm8s]

Bottom part is a termination resistor and the fins are cooling fins .... dummy load on a stick

[@ciscokiduk]

Not had good experiences with this antenna , I no the bands are a bit up and down a to the moment but at 20ft I couldn't hear anything but a
Hash massive noise floor ,I did try a few things but for the cost it's not good ,my well brook loop was pulling things on 20mtrs that this antenna wasn't getting or was under the noise.prob works ok if u live on top of a hill or something.but not for my garden it's packed away I gave up on the thing for now.

[@westtexasvideogateski5juf255]

Thanks for the message -and feed back I appreciate all the comments helps me learn 73 hope to catch you on the air

[@K7LZZ]

I have one....Works decent on HF. On 6M, its pretty poor.....

[@dsolo3250]

Same here. I’ve made one contact on 6 in three months

[@miker8379]

I thought these had a reputation as a terrible antenna
