Re: Siro Megawatt 4000 mobile


I have had one of these over 10 years works better than the mega watt antenna,you can trim the whip to tune to 10m and you can still by the replacement whips.

A good all rounder defiantly. still have mine and i havnt run on 11 metres for about 8 yrs, I'm tempted to come back from HF with these new rigs out emoticon

Re: Siro Megawatt 4000 mobile


The only antenna I've got. I've had some great results, both ground wave and propagation, when used with my Anytone 555.
