A couple of antennas on their way

I have placed an order for two antennas, a Sirio Hi-power 4000 for the car and a Thunderpole Boomerang for the home QTH, these antennas should, hopefully, work to set my base line for CB testing in a mobile environment, the base line is to be set as the Thunderpole T3000, the mobile antenna being as long as realistically possible, the boomerang coming in close to the 'spider antenna' for size.

Of course these antennas get a video on YouTube, the first one will be the Sirio Hi-power 4000 as that is the most straight forward to install, installation will be done at my new radio test ground above Richmond at the Hurgill Road end of the old racecourse.

The other reason I chose the Sirio Hi-Power 4000 is due to the similarity between it and the antenna loaned to me (see a previous video on my YouTube channel) which I since had to return as the amateur that loaned me it needed the magmount, the Orbitor/Springer antennna on the car was always going to be temporary, and the Hi-Power 4000 will work with 10-meters though I would need to shorten it and I was never comfortable doing this with a loaned antenna so it is my intent to buy a second Hi-Power 4000 to be tuned to 10-meters so I just swap the antennas over depending on if I choose to use 10-meters or 11-meters.

For CB, tuning will be done on my Thunderpole T-3000 with the car engine running to ensure the radio is running at it's maximum power output, SWR will be checked across the entire 80 channels using 2 SWR meters, my K-Po meter and my Zetagi meter, these meters will both be used with the boomerang when it goes up and tuning will be done on the Grant II, once this is done my base line can be set, all my radios will go through it, even my handhelds with car kits will be subject to this to see how they perform once a suitable speaker-mic can be obtained that won't jam them on transmit.

I will set up a scoring system for the standardised tests, also with a temporary base antenna I'll be able to retest the handhelds in the local area for a follow up video to "Handheld CBs, are they any good?".
