    Vertical and horizontal beam mounting

    A friend of mine had a 3 element sirio beam horizontally, he purchased another one removed the fittings and elements and as suggested fitted them to the same boom successfully in the vertical configuration, with a switch box at the transceiver he goes from one polarity to the other instantly and...

    11m Moxon vs 5/8GP

    I guess running the coax down the mast should not be as big an issue as using a metallic pole to mount the moxon vertically and after all many yagi beams are used vertically on metallic poles with the coax running down parallel with the elements and they seem to work just fine. Perhaps...

    Sirio GPE 5/8w and GPS 1/2w antennas..

    I have a problem understanding the Sirio basic endfed antennas, namely the Sirio GPE 27 5/8 wave and the Sirio GPS 27 1/2 wave. Here goes! BOTH of the Sirio antennas are 19ft 6 inches tall, the 5/8 wave and the 1/2 wave. Both antennas also come with an additional 3ft odd adjustable steel...

    11m Moxon vs 5/8GP

    I agree the Moxon is a great antenna, I currently use one for 11m, a HPSD one made by Henry. I do have an Imax 2000 also but I'm unable to test directly against the moxon, I do however have a vertical 1/2 wave mounted above my Moxon. Ideally the vertical would be a 5/8 wave GP but this...

    Radials on .64 wave vertical - Straight or angled?

    Thanks The DB for putting the charts up and the work, interesting stuff. I have the radials now on the Imax 2000, around 8ft horizontally mounted at the bottom U bolt (as Solarcon suggests for their GPK kit), I cant actually angle the radials as each radial is one piece made from sections of a...

    Radials on .64 wave vertical - Straight or angled?

    Thanks for the info, all understood regarding the 1/4 wave antennas. It would be interesting to see the modelling of the Imax with and without radials, angled or straight. I came across another forum, copper something? stating that simply moving the Solarcon GPK from 45 degrees to 30...

    Radials on .64 wave vertical - Straight or angled?

    Is there any benefit to using radials angled rather than straight on a .64 wave antenna (like an Imax 2000 for instance), if so what are they? I know angled radials can help bring the impedance down to 50 ohm but the Imax and the likes are already 50 Ohms at the feedpoint (even with no...

    Astatic 10-DA mic for D104?

    Hi, thanks for the info. What kind of element is in the 10-da head? For any other modes other than SSB the 10-DA may not be as good I reckon, I only use SSB here so would still like to try one. Recently I found an easy mod to run the t-up9/d104 off of the power in the radio, so no more 9v...

    Astatic 10-DA mic for D104?

    Hi all, just wondering if anybody has used the 10-DA element versus the standard 'lollipop' one on the D104 desk mic, would the 10-DA SSB mic head be a worthwhile investment? and if so what is the sound difference between them. Thanks

    Marconi comparing New Top One vs. Old Top One

    Thanks for the interesting thread. I got one of the last if not thee very last astroplane/CTE top one clones from a supplier here in UK a while back (a BT101 which is unbranded so I don't know who actually made them, but they are based on the original and NOT the new Sirio Top One). It's...

    Thanks for the welcome m42, Londonderry is just to the NW of me about 50 mile. Got a few friends on the radio funny enough that support the Stoke football team! I was born in England but moved to Ireland in the early 80s. Patrick

    Astroplane with 1/4 wave top?

    Hi marconi, thanks for that link and the info of all your work, that's exactly what I was looking for, it's 12.30am here now so i'll go through it in detail tomorrow when I'm fresher!

    Change user name if possible?

    Hello admin, is it possible to change my username on this forum to bring it in line with a few other forums I am on. I tried to start another account but because it is the same email address it would not let me register with the new name. If it's possible my new user name of SuperNasty (with...

    Astroplane with 1/4 wave top?

    Hi all, I'm sure this has been covered before but there's so much info to go through I thought I'd ask here again. Anyway the question is has anybody tried replacing the 1/8 wave capacitance loaded top section on the astroplane or CTE top one with a 1/4 wave section? In the patent for the...
