By adding the fire up in theory the antenna should then be a 5/8 due to electrical length although mine was 4.49m with the fire up added. Works all the locals easy with better signals than before and the DX when it is in works well. Dave, how did the antenna installation go Mr. M0OGY |

Hi Simon, thats interesting if you're sure the Skipmaster + fireup = 5/8 wave length.. As the original Firestik info page states the fireup is wound as a 5/8 wave but resonant at 32.700Mhz.. Was the fireup you used a genuine firestik part or a Thunderpole version?? I'm still convinced that removing the whip & top fiberglass section of the TP5 / Skipmaster leaves the remaining antenna at just over a 1/4 wave length (2/8's) and that adding the 5/8 wave wound fireup makes it a 7/8 wave in total.. When I popped into Sigma E's to buy my Skipmaster Paul did mention they had tried a fire stick on the top of a skipmaster but it didn't work to well.. This would make sence as the fire stick would be a wound 1/4 wave and with the two remaining sections of the skipmaster making just over 1/4 wave length at 11m the whole thing would have been an over length 1/2 wave resonant at around 24-25Mhz at a guess.. Think I might grab a cheap fire stick copy and have a go re-winding it as a 5/8 wave and putting it on the skippy.. |

I use an original firestik fire up as my tip, thats 5/8 wound and so far. Paraguay Lebanon New Zealand Curacao All worked with 100-200w so seems to work for me. And Paul told me they tested one time in December the fire up idea and had not time to pursue it and now to you " it does not work too well" Well works well for me, id not swap it. I have now here a thunderpole tip but have not tested it as ill and not really feeling like climbing on roofs |

Hope you start feeling better soon Simon, I had three weeks of flu over Christmas & New year so know how your feeling! OK I think I've now got it.. The "fireup" section Paul showed me was (I think) was a normal 1/4 wave wound firestik style mobile antenna NOT a 5/8 wound "fireup" (although I could be wrong!) so this might explain the so, so results.. If your tests have been with a genuine original "5/8 woud Fireup" then that fully explains the excellent improved results over a standard Skippy or TP5.. Hope Paul & his team come up with their own "5/8 fireup" version add on!!! Really looking forward to catching some E's with my Skippy when I'm able to get to the radio and work some DX!!!

Yep 2x anti-biotics here now and still as rough as a badgers arse as some people call it. The antenna here is a 5/8 fire up. It was bought in the USA from Firestik and is wound 5/8 so the packet says. The antenna Thunderpole sells thats made by Sigma is also 5/8 so I believed? Its advertised as such http://www.thunderpole.co.uk/a99-upgrade-stick.html I have a TP one arrived here and will test it and see what happens. I know that it expanded the bandwidth with the original one. Made almost 340 channels usage and not the 120ch that was after the original antenna was installed. I try later this week, if am allowed to roof and feel better thats the more important matter. |

Reviving the thread as have been testing here a new prototype from Paul for the Skipmaster 2010 so will work with the TP5 of course. It is a 5/8 adjustable tip that behaves in a similar way to the Fire-Up that many have added to there Antrons, and here is how the swr behaves UK 80 Channels 12.5cm from cover of tip to where antenna enters the plastic: Covers easily with antenna totally flat @555 German 80 Channels. 10cm and works between 26.565-27405 with swr almost flat between 26.900-27.600 10 Metres, 28300-29600 then use the tip at around 4cm and is fine, flat at around 28.900 12 Metres. Have made a qso there but the antenna is not so efficient, although have the settings it is not worth it. "Big Boys Band" Yes the antenna works there. Tip at around 20cm and works 25800-27200 with flat @ around 26900 Price: Not Known Availability: 2 Pieces Made. I have 1 and Team will have 1 for tests Max Power: I have used 300w FM and was fine. Maximum not known at present time Colours: Mine is White Tested @20km the Skipmaster was S1 up on a Venom 5/8 which was higher by some 20cm. Same RG58 Coax, 10m of said coax and same radio at the time. Team TS 9M Not Scientific, Never Studied Rock Formation, Soil, How the earth turned or cows stood. Just keyed the mike and changed the antenna switch More news soon.......... |

So more info made its way here last night Production of the tip will be, but also will be 5cm shorter and wound more into the fibreglass (new prototype comes soon) Name: Sigma Eurcomm 2011 Skipmaster 5/8 so maybe Thunderpole has a version too?? Cannot tell you Video of new prototype when arrived |

Speaking to Paul at Sigma Eurcomm this afternoon. He is still waiting the definitive testing of the unit [from across the channel] which will then be going into production. He is also compiling a list of those who have registered an interest in this piece of kit. No price yet of course, but it will not it seems be appreciably more expensive than their standard production half wave unit. Sufficiently interesting to persuade me to hold off the purchase of a possibly much more expensive new vertical until the finished Sigma/TP is available. Very much the case of "Waiting large erection! Have nice new shiny mast lying about in need of new antenna". Bandwidth and tuning will be one of the main points of interest. I use 27/28 and so the proof of the pudding etc. Seems worth a punt from what I have read so far. Cheers. |

He is still waiting the definitive testing of the unit [from across the channel] which will then be going into production Yes will work up and in 28mhz with the tip adjusted, If remember correct its either 4 or 3cm. Tests will continue when the new shorter tip is made. 5cm less (easier for packing) and more winds inside the sleeve. When it is made as the prototype then will be here and on the air, on the test and also measurements taken for the banding |

i was told by paul that the new 5/8 sigma would be about £70!!! which is not bad really! also there "COULD BE" a true 5/8 wave size just like the 1/2 wave in the future in stead of wire wound so called 5/8 wave ie a true 20+ foot 5/8 wave!! cool!! |

Interesting, mine was also harder to SWR but when in the air it works all the time, not any issues at all. Antron is a static monster, and with the Imax is the SOLE reason all the Jackson II's keep blowing finals. |
