Hi Everyone

Im after some help and advice please, im looking at buing a TP5 for a homebase aerial with the intention of using it with my Anytone 5555 at the moment that is programmed to cover between

26.065 (s.low) to 27.991 (uk 40), i have been searching around for info and have found that you can cut to the middle of the freq you are using so for me the middle would be 27.000 mhz at a length of 41"...???...will this aerial equally cover the ranges ok at that or am i wrong..??

As a begginer im grateful of any help and advice please.

Thanks

Rich

I don't have a Thunderpole 5, so I'm going from 2nd hand info, but I think you will find that it covers 25-30MHz. You just need to adjust the top section to tune it where you need it to be resonant.

Yes. You want it to be resonant in the middle of your required frequency range - and it will drop off towards the edges, but I don't think you actually need to cut anything ... although I'm sure someone from Thunderpole will be along shortly to correct me. :lol:

Hi Rich,

Yep Guzzy is correct (apart from the cutting bit), you need to cut it for 27MHz which is 41"

The Thunderpole 5 should then cover 26 to 28 quite easily, it may drop off to the edges slightly but nothing to worry about.

The cutting chart is as follows;

Centre Freq. Length
25.500 MHz - 53” whip
26.500 MHz - 46” whip
27.000 MHz - 41” whip
27.500 MHz - 32” whip (use this length for Normal UK/EU CB radios)
28.000 MHz - 28” whip
28.500 MHz - 24” whip
29.000 MHz - 23” whip
29.500 MHz - 22” whip
