guy told that was wrong, if you go direct from centre lead to radiator you will see a very high impedance, and won't get it swr'd, centre lead always goes to tap on coil and shield to radials or base of coil where radials are connected as it is DC grounded. At base of radiator of a 1/2 or 5/8...

The SS3900 is not Uniden made, never was, Either RCI or some other company. the SS360FM was Uniden made, and ended at pb010ab board, Uniden then went on to produce a pb010ac board, but it was neither superstar SS360FM or Cobra 148 Gtl Dx, i know, i have 2 of them, And unlike their previous...

300 / 27.185 = 11.03m x 3.28 = 36.19 feet (freespace wavelength of 27.185 Mhz) /8 = 4.52 feet x 3 =13.57 feet x .66 = 8.958 feet x 12 = 107.5034" or a baw hair short of 9 ft for 3/8 wave stub. just slightly under 1/2 an inch out. Probably insignificant on grand scale of things. unlike your...

I understand that Garth, its the shorted stub that has me curious, obviously 3 elements paralleled that are nominally 72 ohms would be about 24 ohm total if truly resistive which they won't be and spaced far enough apart which again they ain't ideal, so the other 26 ohm must be made up from the...

Funnily enough our Ofcom/Ris are exactly the same, boy did they milk fuck out olympics and commonwealth games and selling off spectrum for mobile phones, but they've hardly been near a pirate in years, not that i'm complaining, LMAO. we have foundation hams openly blasting 100w and more even...

Eddie, you missed Birddog say the coax were 9ft, with a velocity factor of .66 that makes 12 ft a halfwave repeater and 6 ft a 1/4 wave inverter, 9 ft lies exactly 1/2 way between a 1/2 wave and a quarter wave which is a 3/8 wave, the manual states clearly not to change these lengths...

It's also switchable to Omni Directional when all 3 elements are active.

its funny how those laws only apply to amplifiers, yet any easily modded hf set with a 100w linear in it, sails through and will just as effectively put out 100w on 11m, makes you wonder how much the radio manufacturers are back handing the FCC, seems to be the same consistency on radios under...

would be better using 83-1sp or 82-822 with ug175 reducer than those, they really are for emergencies, or westlakes sells ps gland ones, thats where i got greenpar ones, one day i'll dig them out and post pic of them, top quality, rg223 is dual silver plated braids and silver plated conductor...

Can't go wrong with 83-1sp, but 83-822 are better, ptfe dielectric, not much price difference try mouser uk ;) if your ever looking for them and can't find them, search amphenol's website they have a parts inventory of all stockists , need to get some more myself, as got 100m of belden rg223...

Probably, Lmao, I hate shoddy workmanship, i watched a carpet layer lay linoleum for 10 mins 15 years ago, have laid all carpets/lino myself ever since, i learn fast, especially if it involves saving money, the people who taught me about pc's 7 years ago, bring them to me now to get fixed, i...

, I live 500 yards from Clyde Estuary at most, can walk in 10 mins and be on shore, could have an antenna up within 30 mins of leaving house, i can also access hills 200m high in similar timescale, where i live the sea and hills are very very close, but tbh, when it comes to dx, if i get my...

I've dx'ed at the seafront many many times, both right at the shore, also from Mull of Galloway, all down west coast and from all the hills behind it, i've also dx'ed from the many sea lochs in the Clyde estuary, and believe it or not from Blackpool prom too as my aunt owned a guesthouse in...

on the bright side, it might mean less spectrum pollution emanating from 11m, surely that can't be bad and is a relatively cheap route to some hams getting a bit of power going on 10/12m without expensive hf sets and 100w drive amps. must be better than the dirty cb amps used currently.

no reason it shouldn't, good quality coax and a good quality antenna, what more can you ask?

Stick to 9ft, you won't go far wrong as long as its rg58 or rg223 you use. If you try to use different coax and don't understand what i just explained you'll run into problems ;) Good Luck, Jazz 73

in fairness original poster had a few questions before parting with hard earned readies, any good company here will take time to talk to you on phone and many will just chat unless they are really busy, i know its a smaller country, I'm talking biggest dealers in uk here mind, on a radio sale of...

I'm sure Conor knows me well enough that when it comes to cable and connectors I know my shit and have done for 100011 years, guess I'm one of the ten, lmao :thumbup: I know exactly what they are I have about 1/2 a dozen in sealed bags here, and I'd swap them all for one 83-822, or one...

After reading rest of the thread my take is unchanged to original one. Jazz 73

You be puffing same shit I am?:thumbup: lmao :thumbup1:
