The same way you decrease the resistance of anything else ... by providing more parallel current paths. That means running more conductors, and increasing the surface area of contact between your ground system and the earth.
But let me ask you a couple of questions in return:
1). Since the lightning current already flowed through a couple thousand feet of air before it reached your house, do you really think it will notice whether you have 1 ohm or 2 ohms or 5 ohms in the rest of its path to ground ?
2). Aircraft have really good systems in place to protect their avionics and communications from lightning. What do you suppose is the resistance of their systems to ground when they're in flight ?
Just asking.
Maybe there are other things about the grounding system that are more important, and have a greater bearing on the quality of your protection, than a few DC ohms in the path.

What is international standard for electrical grounding?
Less than 1 Ohm.
What is the total resistance of a 6-ohm resistor and a 12-ohm resistor in a parallel series?
In series like so ---6 ohms ---- 12 ohms --- , the total resistance is just 6 ohms + 12 ohms.assuming you mean in parallel like this:_|---6 ohms-----|-|~|-_|---12 ohms---|then the resistance of this can be calculated like so:1/6 ohms + 1/12 ohms = 1/R (where R is the resistance of the circuit as a whole)2/12 ohms + 1/12 ohms = 1/R3/12 ohms = 1/R1/4 ohms = 1/Rso R = 4 ohmsA few notes, if the resistors are in parallel the total resistance will always be less than or equal to the lowest resistance in parallel (i.e 6 ohms in parallel with 12 ohms will have resistance less than 6 ohms).Also if two resistances in parallel are the same, then the resistance is half of the resistance of both resistors (i.e. 1/2 ohms + 1/2 ohms = 1/R; 1 = 1/R, R=1 ohm which is half of 2 ohms).This process can be extended to 2 or more resistors in parallel.i.e if we had a 6 ohm, 6 ohm and 12 ohm resistor in parallel we could go1/6 ohms + 1/6 ohms + 1/12 ohms = 1/R(1/6 ohms + 1/6 ohms) + 1/12 ohms = 1/R1/3 ohms + 1/12 ohms = 1/R4/12ohms + 1/12 ohms = 1/R5/12 ohms = 1/Rso R = 12/5 ohms or 2.4 ohms
Is one mega ohm less then 1 volt?
Like comparing apples and oranges. Ohms are resistance to electrical current. A megaohm is 1 million ohms. Volts are measurements of electical potential.
What is ahigher resistance 10 ohm or 1 kilo ohm in other words does 1kilo ohm have more or less resistance than 10 ohm.?
Because 1 kiloohm is 1000 ohms. 1000 ohms is a higher resistance value than 10 ohms.
What is the proper abbreviation for 1 million ohms?
1 million ohms are 1 megaohms.
What is the resistance of a parallel circuit with resistances of 2 ohms 4 ohms 6 ohms and 10 ohms?
R = 1/[1/2 + 1/4 + 1/6 + 1/10] Add up the reciprocals of the resistances, and take the reciprocal of the answer.
How many ohms is one killow ohm?
1000 Ohms = 1 kilo (not killow) Ohms
Does 1.0 k ohms have the same value as 1000 ohms?
Yes, 1 k-ohm means 1 kilohm or 1000 ohms.
How would you use the word grounding in a sentence?
Like this: "I am grounding my child for 1 week."
How many ohms are in a gig ohm?
How about the same number of metres in a kilometre? Like say 1000
What is a tube microphone?
The tube or the FET transistor is used to build an impedance converter from the high impedance of the capacitor (condenser) of about 1 Giga ohms or more to the low impedance of the microphone output, which is less than 150 ohms.
What is the correct fuel gauge for an 89 yj wrangler option 1 240 ohms full 33 ohms full or option 2 73 ohms empty 8-12 ohms full?
87 to 90 YJ fuel guage sender is: 0 ohms = empty; 44 ohms = 1/2; 88 ohms = full
