Hello all. Been a long time since I’ve been on. I recently came across a Moonraker 6 that’s been sitting in a garage for many years not being used. Great shape the guy says and everything is there. I have 2 questions as I’m unable to dig up any information.

1. What wattage capabilities does the MR6 have?
2. Can I stack a ground plane on top of it (Maco V58)? If so, what do I need to do so?

Thanks guys

Avanti advertised the Moonraker 4 (AV140) at 1000 watts power handling. I am sure they used the same gamma matches on the Moonraker 6 (AV146) so power handling would likely be the same.

Years ago (25+) I installed a Moonraker 4 on a 70 foot tower with a ground plane above it (same mast). It seems a 12-15 mast above the boom was used, worked and tuned well and as far as I know it is still up and in use.

In hindsight a fiberglass mast to support the ground plane would probably have work better.

Link to AV-146 instruction manual below.


Good Luck.

Thanks for the reply. Do you know of anywhere that makes a current production gamma that will work on the MR6? Or will I have to search the web until I find one from years ago? Thanks.

Below is a few links for Maco High Power Gamma Matches. I can't say if they will work on the Avanti or not though.

Thanks. I will look into that. Also, I found these on eBay. Seller has high feedback. Do these look correct?

The ebay ones look like they should work. The Maco ones I would think will as well. One thing you have to look for on the old Moonraker antennas are the hubs being cracked. Also lots of folks used to pin the hub to the boom so they don't move.
