My son ordered a Sirio Tornado 50-60 as a Xmas present for me. On opening the box on Xmas day I was presented with the correct paperwork for a 50-60 but the wrong antenna, they sent the Tornado 27 by mistake. Bob85 and myself discussed the options, it was either send it back with $25 shipping...

Got a Sirio 827 with broken radials? Got a 827 that's gone open circuit? Fear not, there is life in the old beast. I've taken an 827, removed the matching coil and turned it into an half wave dipole. Basically, removed the radials and matching coil and set the element length at 17 feet to begin...

Can anyone tell be the outside diameter of the bottom and middle sections of the fiberglass on a Antron 99? Thanks

Bought one of these recently and thought i'd give it a quick write up. Out of the box they are the smallest rig out there at 4x4x0.8 inches. I'd watched a few video's and read a little about them especially one from Simon the wizard who gave it a good write up. Paid £44 for this rig to the door...

antenna choke

Just recently converted a 650W computer power supply for use with CB equipment. The supply specs were 2x23amp 12v+ on the 12vdc rail, 30amp on the 5vdc rail and 20amp on the 3.3vdc rail. Desoldered the 3.3 and 5v wires off the board apart from one 5vdc + wire which I needed for a shunt resister...

Minutes taken from the Sirio December 2007 meeting:- (names have been ****'d out to protect the identities of those who chaired the meeting. Director ******- We are here today to discuss a possible new antenna design in the Sirio range of 10 and 11 metre designs. However, the rising cost of...

Just had this donated by a guy at work, turns on ok, TX/RX no problem until you've been TXing for 2-3 minutes then radio goes silent on am/fm/ssb. No RX or TX, turn the radio off, leave for 10 minutes, turn back on and radio works fine again. You can listen to the radio without TXing for about...

When Sirio made their 'Top one' antenna I couldn't help noticing the basket was made from the same materials as the Vector basket but the basket was inverted. It became obvious to me that Sirio was using surplus parts from other antennae to produce new models. Then we get the media hype that...

There are many pitfalls in testing one antenna against another. I have performed several tests over the years comparing various antennae mainly verticals. Firstly, I am not going to consider factors such as potentials for electrical ground because I don't think they are relevant to these tests...

Thinking about turning my 827 into a dipole in the same arrangement of the Gainmaster but a few things are bothering me. Firstly after reading what Shockwave says about the choke not being a rf choke but actually determining the length of the lower half of the dipole I can see some problems in...
