I now have both antennas that I ordered, however the Thunderpole Boomerang antenna was to be delivered by Parcelforce (or Parcelfarce as I call them because they are incredibly useless) and they failed to deliver it to a neighbour as instructed, ignored the fact I rescheduled and left it at Catterick Garrison Post Office meaning after filming the video for the Sirio Hi-Power 4000 (and subjecting it to 70MPH due to a trip to nearby Darlington to do a bank run) I had to call at the Post Office to collect it, with that done editing work was finished for the Sirio antenna and the Boomerang unboxing video was filmed.
A big surprise with the Sirio was that I did not need to adjust it, SWR under 1.5:1 across all 80 channels, for the most part, the top end of 27/81 was about 1.4 which is acceptable, I was to compare between my K-Po and Zetagi SWR meters however this did not happen because another vehicle parked next to my car before I could do that, and the driver did not seem happy that I was even up there, probably because I don't own a dog, unfortunately public land means I have a right to go up there, it is ideal for radio given height and forms part of my mobile standardised test route, now I have the antenna I will be doing a dry run on video before actually doing anything on the air to show you the route from the car.
The only part to do from the perspective of the new antennas is the on-air test of the Boomerang, once it is up and tuned, given the fine adjustments that may be needed I won't bore you and give a final SWR reading as per the K-Po meter, the Zetagi meter, and the one built in to the President Grant II.
I will be working from 4pm tonight and as ever will be monitoring UK 19, which is usually full of the burner brigade running illegal power to speak to their pals which the 4 watts can do fine for them but they generally don't have a good understanding of this fact, that and they have the squelch turned all the way up which is a bit ridiculous really, maybe even with them I may notice a difference on this antenna on receive, the one thing that will be noticed is the fact I have a bigger antenna on the car.
