Hi - This is Rich, W2FKN and I just installed the exact antenna you have described so very well. Since I'm in an HOA community I cannot mount the antenna on my home. It is attached to a very secure pipe arrangement in a landscape area behind my home anchored in an 80 lb concrete block underground. It is mounted only 8 feet above the ground and very well guyed. Connot be seen from the front of my home. Works well even though it is only 2 feet from the back of the house. Great SWR on my FTDX5000 MP Limited - essentially 1 to 1.2 or less throughout all bands. They have no problem with it - Gets out damn well - 73.
Looks like we have a lot in common. I have had the CHA-250HD installed for over 2 months and am using the FT-991A, too. The antenna is mounted to a steel pole only 6' above ground. I've been very pleased with the antenna's performance, as well. Much better than I expected. 6m -1.3 SWR / 17.7 dB loss 10m -1.07 SWR / 30.0 dB loss 12m -1.01 SWR / 43.0 dB loss 15m -1.05 SWR / 32.0 dB loss 17m -1.13 SWR / 24.0 dB loss 20m - 1.37 SWR / 16.1 dB loss 40m - 1.64 SWR / 12.0 dB loss 80m - 1.8 SWR / 10.9 dB loss KE8VEG, 73s
Good evening and thanks for the message and test results yeah for me its all new this is my first experience in the 15 through 80m I've always done 10 and 6m - Yeah I've had good RST on 80 through 17m there's a net on 3916 at 7:30 PM CST I was able to talk to folks all over Texas - okay thanks so much for the message I am very happy with the results, if you want email me shope02@yahoo.com I'll send you the data sheets with the take angles and dB loss at 10ft and 35ft for all bands I don't fully understand but I'm happy with the performance. 73 and hope to make a contact on the air !
Had the original CHA-250b. Good antenna until I moved to West Texas where the wind bent it up pretty bad. I DO wish they would make one that can handle more power... Maybe handle 600-1000 watts. Might look for a CHA-250HD at the Belton Hamfest in a couple of days. 73! W5ODP
Good evening Dave, thanks for the message, yeah so far I've been lucky with the wind - yeah higher power would be nice - ok have a safe trip if you go to Belton, let me know if you need anything from me - 73 and have a great weekend!

Wow -looks like you can use it on every band including 5 MHz!

Looks like a well made antenna that should perform well. The only challenge some might experience is installing it at such height.
great and usefull data. Nicely done. I picked one of these up 2nd hard - looking forward to setting this us!!!

Can this be used on GMRS?
What is the SWR readings at 462.000 - 468.000?
No. GMRS would be just above the 70cm ham band. This antenna only works 80m-6m
I have one up 40 ft and it doesn’t work it is death my a 99 works better
